mp4 files are not an ideal editing format. You might try transcoding to a more robust format like prores and see if that solves the problem.
And by any chance are any of your sources from a screen recording or shot on a smartphone? If so, issue is probably that some of your sources have a variable frame rate which can cause wide array of problems that are inconsistent and hard to predict. Here's how to fix this issue
use mediainfo to determine whether your source is variable or constant frame rate
