Up and down cursor not editing my midi notes

I’m not sure exactly what i’ve done, but when i use up and down arrows to try and move my midi notes instead it ignores the midi notes and scrolls along my tracks, i’ve double double checked that “Use up/down commands for navigating tracks only” is not checked, its definetely 100% not checked, still when editing my midi files the notes won’t move up and down. If i use left and right the notes move as expected.

Any other place i need to check to get my up/down arrows to edit my midi notes again?

Thanks!
