I can't un default group zendesk bug ?

Hi there,

Zendesk uses the term "default group" in two different contexts, I think this is causing this confusion. When you edit this group and try to remove users who are members of this group, you are told that you cannot remove two of them because this is their default group.
You need to go each of these two users profiles and set a different default group for them before you can remove them from this one. You can remove them from the group from the profile as well.
Hope this helps you out.
