My kickflips turn 90 degrees?

[IwannaLernItall]

Everytime that i do a kickflip my board flips 90 degrees almost every time. I dont know why it is doing that. I have only landed 1 kickflip and it was an ugly one.

Make sure to keep your shoulders straight with the board and pop the tail clean and nice.
