Additional context

A screenshot to illustrate the issue.

I have watched video A and B.

1. Video A could be hidden if I press the eye button "Show watched videos" (second button top right);
2. While video A got a red progressbar on its thumbnail, video B didn't.

But from your screenshot the Video B isn't marked as watched (See the bottom red bar)

The problem seems to be BiliBili videos are not correctly marked.

Will be fixed in 4.3.0.
