Recommend section shows video already seen

[The5ilverGod]

So ice been using playlet for a bit now and the recommended section is usually filled with videos I've seen already if if others have this issue is the s way to fix this?

I believe this is normal, YouTube suggest videos even if you've seen them again, sometimes because you didn't finish them yet, and sometimes it thinks you'd want to watch again.
I don't believe YouTube's algorithm is customizable, or that Playlet can do much about it
