Try creating a new group and base it off of TDAdmin, alot of times even though you add permissions on a group it does not work correctly unless the group was based off of TDAdmin originally (this is an old ALM glitch that affects some versions of QC10 onward) even though you add the permissions to a group it wont give the user those permissions even though you selected them. It is better to create a new group and base it off of TDAdmin and remove permissions rather than create a group based off of say ''performance'' and add permissions.
