Cannot create collection in library

Since 10 days, I cannot modify the game title and player name (W and B) Please fix
That is being looked into by staff.

For me it is different. I can add games to my library (and can create new collections without any problems) but I cannot rename those games within them (and there is no error message at all for me; it says "saved" but it doesn't actually save). I initially thought this was a server problem that was connected to the trophy counter freezing that one day but I was wrong. I think all of us are having different layers of the same library problem (although I don't know how that's possible).

There have been different bugs.

Well I think they fixed it but mine isn't working again, same error
It's broken again, outside of beta. I have let staff know.
This seems to be working now.
Yes, it's working for me, too. Thanks for fixing it, chess.com.
There's a feature in the Library which is broken. After adding a game to the Library you can edit that game to add a game title. After Save, when the Edit box is opened again the game title is missing. Can this be fixed, please?
I mentioned that to a staff member yesterday, so it will be looked at.
