Yes, It's not the only thing that's wrong, hope devs will get to fix that.

Fire main's Bani Chakra gives incorrect info in game (it always gives 40 chakra).

Earth main's guaidance works only on male ninjas (no info in game).

Edo Yagura's passive doesn't make any sense (it's Edo Roshi's passive).

Gamachu's non upgraded summon mystery says he will give attack buff (he gives ninjutsu buff).

And a lot more which I can't currently recall... Some things don't matter much, but some can be pretty misleading.
