Ok 2 things. Where do you set that “GetOffBot” because if that doesnt go to true, then you never set the movement mode back to walking, and your floating makes me suspect your still flying. Also, I would think the if axis value < 0 should become <= 0. Since simply letting go of the thumbstick should stop you climbing.
The reason Jump would fix you is the jump will switch you movement system to falling and therefore clearing the flying flag.
