Usermanger user login fail when user assigned to new customer

Mikrotik HEX 6.48.2 Cap enabled, Hotspot, Raduis (user manager installed)

When a user is created by an customer (other than admin) and the user tries to log in he get’s an error user not found.
When I change the owner of the user to admin the user can login.
Custommer permissions are set to full.

What goes wrong?

Thanks
