When I try go grant permission to a user in a new web I don't get listed the cusom groups on the current web. 

If you look at the image you can see that the list in the background are quite a bit larger than what I got listed in the dropdown-list "add user to a sharepoint group". What's wrong?

I've also having problem that sharepoint groups that's been removed are showing in the same dropdown-list
