Nikya of the Old Ways - Mana Gain Question [Fix in 3.4]

So, after trying out Nikya in a Karn deck, I did not see my colored mana gains increase in any discernable way. It did not give a +1 on his Ability Activation Screen, and there wasn’t a notable increase when I matched gems.

Am I missing something, or is it not working?

I just played her with Angrath, and got no mana buffs.

Hi everyone, a fix for this issue is currently scheduled to be released in update 3.4.
