Scenario:
Host groups called 'Prod'. Two user's groups: 'Admins' and 'Alerts'. 'Admins' has RW rights for 'Prod'. 'Alerts' has RO rights for 'Prod'.

Issue:
If I add user to both groups, user looses RW rights for hosts in group, if I remove user from 'Alerts' - everything is OK, user has RW rights.

Is is normal behavior of it's a bug? I haven't been able to find anything about this in documentation.
