When there are no Teams, Systems, and System Groups, the buttons that appear under Users > Edit are not consistent. For example, when no systems are present on TrueCommand the buttons "MANAGE SYSTEMS" and "ADD SYSTEM" appear, but "ADD SYSTEM" does nothing.
EDIT: This also applies to Teams > Edit.
See attached screenshot.
SOLUTION: Simply remove "ADD SYSTEM" when no systems are present on TrueCommand so that it is consistent with "Joined Teams" and "System Groups".
