It wasn't an issue in the Voyage Home because had that event of time travel not taken place, Starfleet Command would not have functioned to give rise to the Federation of the 29th-31st Centuries; given that Giant Penis Probe shutting down all technology around it's range; hence, that time line didn't exist in the first place to prevent a temporal incursion(Woot, temporal paradox):
Sorry I seem to have missed something but how did the 29-31st centuries come into The Voyage Home?

Im quite sure that the timeline has no conceptions of intent, whether intentional or accidental, any change in the timeline would be detected and dealt with. Furthermore, Star Trek Enterprise's feature of the Temporal Cold War showed that Starfleet was involved in preventing changes to the time line at the hands of forces beyond their own, thus leaving nothing to state that they would not intervene if the Romulans officially sanctioned a temporal mission, or a rogue sought to pull it off.
The things is even of they did try to prevent changes to the timeline.. they couldn't as it just creates parallel universes..the unibverse of TNG still exists it's just not the one we're following now with the new Trek stories
The 29th-31st Centuries are known to be the peak(at least from our perception) of the Federation's capacity to monitor and utilize the time line; while there are instances of federation use of the time line in the 27th and 28th centuries, the 29th century is one we are most familiar with when taking Voyager into Context, and the 31st century is most notable in time travel capacity when taking Star Trek Enterprise into context. The Temporal Prime Directive would have been utilized to prevent incursions that affected their time line.
In Temporal Mechanics, if one goes back in time and changes a moment by modifying an incident or instigating it, it has repercussions throughout the timeline, giving rise to a new timeline that would take over, as the events that led up to the temporal incursion would change dramatically, it would not create 2 parallel timelines, as one has to supersede the other, generally, if left unattended, the paralel timeline that is the result of a temporal incursion takes precedence: For example, an episode in Voyager highlights the dominance of one timeline that leads to the 'destruction'(or rather, modification of a significant moment that shapes future events, thus rendering the alternative timeline as 'fixed') Voyager uses a Slipstream Drive to get home, it requires the Delta Flyer to go on ahead of Voyager in the slipstream so they can relay modifications back to voyager and keep the slipstream stable, they fail shortly after, voyager is hurdled out of the slipstream and crashes on a Class L planet near the border between the Alpha and Beta Quadrants. The alternate timeline thus consists of Harry Kim, and Commander Chakotay, living a few decades after the incident that got them home. They resolve to fix the situation by using a borg temporal transceiver, to communicate to Seven of Nine in the past, and send her the correct phase variants necessary to keep the slipstream stable. The first attempt fails, however another try with a different intention follows, Harry Kim sends data that effectively shuts down the slipstream(while sending a warning embedded in the transmission.) Having averted the crisis, the timeline the future chakotay and harry kim exist in ceases to be as Voyager is not destroyed, but rather, lives to move safely back to the Alpha quadrant carrying it's data, technology, and more importantly, people whom produce children that populate the proper time line.(If you are going to ask why Starfleet didn't prevent this temporal incursion, I would argue that the capacity to study and modify the timeline owes a bit of it's knowledge and protocol to the life of voyager and the information it gathers while in the delta quadrant, lets not forget that they cripple the borg in the last episode, giving the federation some breathing room to expand and gain a stronger advantage{which would also explain why temporal agents did not intervene when a future Captain Janeway goes back into the past to give Voyager a shortcut home, through the transwarp hub, while sacrificing herself to do that crippling blow to the borg via an infectious virus})
