Unable to Rank user's in Groups

Alright so, Im facing an issue where im unable to rank users in my communities (groups) or in communities (groups) where I have the permissions required to rank members. I believe this a bug or smth but I cant find a clear solution as most of the fixes ive seen are from 2020-21 which are for other errors.

What’s happening is, When i try to change someone rank, It shows the error on top.
From what I see, I think its only affecting me? Or am I doing smth wrong here?

Hey, try verifying your internet connection that might be the issue. Also, the problem could be that you incorrectly moderated the role title when a space was added.

I don’t suppose it’s a internet connection problem as the issue has ben occuring for a bit of time now and it would’ve been solved if it were a internet issue.
As for the role title thing, I dont get what you mean by “when a space was added”
