Problems with jumping/ landing

Hi! I´m making my first thirdperson-game and I'm having a problem. My jump animation/ transform worked just fine when I didn't have any landning animation, but when I added a "roll" animation as a landing, the jump animation started to bug. 2/3 of every jump is extremely high. Why does this happen?

Sorry if my grammar is bad but I think everything understandable...

I uploaded my game at itch.io right here. And remember that this is just a pre-alpha on the demo thats never gonna be a real game. I'm just learning.

Thanks.
