Trying to understand what you mean here!
So you blocklisted the user (Ivystar5) and search for the username again it showed that you have blocklisted me but then you searched on find member only to see that Ivystar5 when clicked on is showing (xOrpian) ?
I can't really figure out what exactly went wrong but I guess if it was a link you clicked on and not the username then you would be and omission in one of the letters.
If I copy paste 'xOrpian' directly in field and save it, then yes it's saved. But when I copy paste the same username 'xOrpian' in Find Member search field and click username 'xOrpian' there and I click xOrpian then a username is added to the ignore users field (THIS USERNAME is not xOrpian but something else) - And yes this username doesn't finalize post saving the ignore/block list.
