Disabled Users not visible for the Administrator #8917

The same issue as in #6809 . But there somehow declared as not the same issue...
So this is a new ticket:

Steps to reproduce

1. Log in as Admin (Full Admin not Group Admin)
2. Go to Users and Disable an existing User
3. On the left pane select the Group "Disabled"

Expected behaviour

The Group "Disabled" should list disabled User Accounts

Actual behaviour

The Group "Disabled" doesn't list the disabled Users. The amount (number) of disabled Users is visible.
