Can anyone explain why audio channels become unsynced?

I am on 25.1. This is obnoxious. For some reason audio I have manually synced, comes unsynced from eachother seemingly randomly. I have manually fixed the entire video like 5 times. Both audio tracks are lined up with the end of each clip and that ever changes. The only thing that changes is I move the video track and two audio tracks at the same time. Then I'll zoom all the way in and look at the wave form and it will not be where I adjusted it. I've never encountered this problem before and I am now dreading doing any kind of audio adjustments until right before the final render. Is this a known problem? This is my first project on Premiere Pro 25. 

Linking the channels is not an option as they require seperate effects.
