Thumbstick strange behavior

hi, i’ve got a very strange problem that i can’t resolve alone.
i have created 4 thumbstick: 1 left for direction and 3 right for shoot
they got the right axys and work similar to stickshooter example project( axys and rotation value) but there is a little problem now, when i release button the player cast in right direction the spell and…work fine in all direction without extreme left and extreme right of the thumbstick y=-88 +92 approximately and Y= +92 +88 approximately cast nothing. Same value of axys and rotation as example project but character do nothing only in this thumbstick position
I can’t understand this, how can solve ?
sorry for bad english
