Android bluetooth controller

[bembmx]

Ok I looked but could not find any help so sorry if this has been brought up. I am currently using the newest version of the Android app. I am trying to map my controls. While mapping it will see all the controls and acknowledge the input. Once I start the game it will not let me go up or down on the D-pad. Is there any reason for this? I tried two different controllers and it wont work. I am not sure what to do. It is frustrating. Touch controls are not bad but a gamepad would be so much better. It appears all the other controls work but up and down.
