Audio volume suddenly maxed during editing

So while I was editing my video (I’m already about 3-4 hours deep into editing while I’m normalizing the audio) suddenly all the video clips audio is maxed out and distorted even after removing all the audio filter on all the video clips it still remains maxed. I now have to use the gain filter to lower the volume on the videos so it’s not maxed out and distorted. I have closed the app restarted my computer and still remains maxed out on the timeline.

Does anybody have any clue what happened??

By the way running the latest version on the latest version of Linux Mint.
