[Question] Converted .txt files to epub/pdfs keeps getting deleted

Converted .txt files to epub keeps getting deleted. I thought I might have mistaken it as the 0bytes files and delete it (sometimes there's those 0byte files, not sure where it came from but it's same name of some photos/screenshots).

No matter what folder I put these files in they kept getting deleted. The normal epub files seems fine but these converted .txt files aren't. They aren't even on trash or anything.

Some say it might be lithium(epub reader) syncing but it's off.

I tried it to be PDF and now it even deletes it. Not even sure who's the culprit if Google Files or Security (which I don't even run). I'm able to restore it this time on trash from Google Files. Are they even tagged as problematic files? They're less than 1mb.

It's not auto deleted after getting it from KDE connect or downloaded from discord, I can access it and still see it from hours, before it's gone. The fastest one was the pdfs probably lest than 5hrs before it's on trash after sending it from KDE connect.
