More than 1 user to manage category

[Pixels]

Hello,

I've been trying to setup a category as follow:
Category Files Front-End
Visible to registered users
Download access to registered users

Category Management Front-End
Upload Rights: StaffTeam (Group1) or at least Staffuser1, Staffuser2
Delete Rights: StaffTeam (Group2) or at least StaffManager

Do I make sense? Every time I try to select more than 1 "username" from the upload rights list. It deletes my 1st option and just leave the new user.
Also It only shows "Nobody" or "All registered" Which I understand are groups. Right? Any help will be GREATLY appreciated.

Hi, it is multiselect field, if you hold CTRL, you can select more user.
