This issue should be caused by corrupted group name. Especially, it may happen when there are trailing blank characters (trailing spaces etc.) in a group name.
Solution
Check if there is any corrupted group names in any tables of https://confluence.atlassian.com/confkb/how-to-rename-a-group-and-preserve-its-permissions-948228977.html
If any wrong group name is found, run the update SQL in the KB to correct them.
