Issue with adding Windows AD groups

Hi,

having an issue adding a windows AD group to my Orchestrator. I have already added this group in the past, but now there are users added to it so i need to re-add the group to grab them. When I try to add the group, it adds the group like its a user, and isnt grabbing any of the new users. Once its in there, I do not have an option to remove it

Any help would be appreciated, thank you
