YouTube isn't letting my remove deleted videos?

So, I have a few deleted or private videos in my Liked Playlist on YouTube. When I try to click 'remove video' it tells me, "request contains an invalid argument". What does that even mean?? There is no argument! I want it removed because I literally cannot watch it anymore! I have no problem deleting regular videos from that playlist. It's just the private or deleted ones that refuse to be removed and I don't know why. Anyone else having this issue? Anyone know how to fix it? Please help it's driving me insane!
