Controls bug?

I am having an issue with hidden controls that override my controls. For example I was in a test drive with a He-111H6 dropping the fritz X and the guided bomb worked perfectly until I dropped the 3rd bomb then it started controlling my plane instead of the time. my bomb and missile control key is the arrow keys.

the 1st 2x bomb drops were in 3rd person and the while the 3rd bomb was in bomber view when things stopped working. I checked my controls for the aircraft and I did not see arrow keys on the list.

Before I have had issues with a lower key on the keyboard which prevented me from setting anything on the key but I forget what key it was or what it did but I remember it overrides the controls I set to it which made me not want to play top tier because I cannot set up my controls the way I want.
