The slot index might be messed up.
Just remember, that the VIP and so called GM masteries ain't masterpieces. Only some amateur cloning of existent skills with no unique or special options nor behavior, with weird and doubtful animations. For people saying that clicking on add won't trigger anything, missed the groups? If not, recheck the page, slot, row etc. of each skill and add them as same to the client.
It isn't that hard doing so, cmon.
