We have a strange scenario in the webi report as following:
1) We created a group ABC and then custom sorted by including this group and others as well
2)Renamed ABC to AB.
3)Now in the custom sort list both old and new groups are visible,i.e, ABC and AB.
Is it a normal behavior? If yes then how can it be rectified as client only wish to see the groups they have renamed. It is also not possible to reset the list which solves the renaming issue but involves rework in defining the sort again.
