Audio is synched on preview but unsynched on export

Elements 2025: When I'm putting together episodes of our gaming show, we have the game footage with game audio, and our commentary audio track. After importing both files, I will manually line the two up with a sync point. This will get it to an "Almost synched" state, where they're not quite lined up yet and the two audio tracks clash slightly. I check a later point in the file and realize they're not aligned right, adjust one track over a few frames, and now they're "Perfectly synched". I will playback the movie on Premiere's preview window and everything sounds perfect. However, after I export the movie into a file, what gets exported is the earlier "Almost synched" version. I have no idea why this happens. there's no reason this SHOULD happen, and I have no clue how to fix this. Deleting the media cache doesn't help, and sometimes but not always the problem just seems to magically fix itself. I'm blown away that there exists a problem like this where the output file DOES NOT MATCH what's played in the preview window. PLEASE help me fix this or I'm going to lose my mind.
