When trying to delete a group I need to enter my password. It does not work, I receive the error message

"Confirmation password is wrong".

I have logged out, logged in again with the SAME password, it works. I entered the password into Notepad first, copied it, it works for login, not for confirmation. I changed my account password, logged in with it, it works. If I use it as confirmation password, it does not work.

Am I doing something wrong?

Thanks!
