This has been a problem (I'm assuming it's a bug because of how the issue is behaving) for over a year and I've seen very few people talking about it. I don't know about the (affected versions) question so i probably answered that wrong, all I know is I'm on Playstation 5, and I'm on V.1.20.32.

Bug: I'm missing a pair of eyes that i was using on my custom minecraft characters. (They aren't custom made skins, just the free sets that I was able to equip on the "Body" tab. I tried looking in the body tab of the character creater, and I don't see the pair of eyes I was wearing anymore. I see new sets of eyes that I had never seen before but the ones that I had set are gone and now my characters have no faces. As far as I'm aware, I did nothing to cause this, I just logged in one day and then boom, no faces. 

I remember the eyes name, they were called "clown eyes" or "clown makeup". They had one dot for the eyes and a cheek blush option that you could change the color of. In fact, one of my characters still have the eyes equipped, but all the others don't. So It's very clear to me that the eyes did once exist, and still do, but the option to put them on is no longer there. Their are still remnants of the eyes left in the system. I didn't want to touch the last character left that had these still had these eyes equipped so that I have proof. In the screenshot I have attached you can clearly see that one has green dot eyes and a blush on her face, whereas the others don't have anything on their faces at all that used to have the clown eyes on. I really hope this is a bug or a mistake because I really liked those eyes, I don't appreciate them being removed if that was the case.
