Is this access level a sub level of a higher access level? In that case that access level would inherit all access from it's parent level.
If that's not the case and you have a valid Essential or Enterprise subscription I suggest you raise a support ticket for this (https://www.acymailing.com) so we can have a look at it. Please include login credentials for your backend.
Edit: just noticed this crossed your previous reply. Please raise a support ticket as suggested.
