Karma ULTIMATE and COIN QUEST

I experienced an issue with leveling up my karma ult after achieving the quest connected to the new medallion/coin item. Once I complete the quest before level 11, usually around level 8-9, I can no longer scale up karma ult. Meaning that she can only have 2 points in her ult, as opposed to 3 at level 11, her being the only champion that can have that many at level 11. How to re-enact it:

1. Pick Karma 2)Get Coin item and upgrade it, then finish its quest (before level 11)
2. Try to rank up your ult once you get to level 11...(It doesn't let you)
