User Access Group is behaving abnormally and taking over Administrator Rights.

[pnayan436]

I have recently added on user access group and that group is taking over "Administrator Rights" without getting assigned. Also, all the other existing user access group has been repeating multiple time. The internal ID for it are considered 0.
From the user side, there's not fix available.

Looks like problem with database. Check app_access_groups tabel in phpmyadimn. The flag AUTO_INCREMENT should be assigned ot ID column. See attached.
In phpmyadimn you can remove duplicates.
