YT Shows wrong suggestions

Yesterday I downloaded (and scraped titles, kws, etc) more than 100 videos to bulk upload (to 25 ACCs). I uploaded more than 50 videos today, but youtube shows wrong suggested videos (at right side) and so all my videos are not related to my niche. I tried to upload without link but faced the same problem. Anyone have suggestions?

I use MVB

YouTube changed their suggested video algorithm, that's probably what's affecting your thing too.
