BUTTON A JUMP/UPGRADE

This may be my problem, not BF6.   I play on a PC with a Manba X Box style controller.  When I am at an opened case and want to claim an upgrade, I press and hold  "A".   But recently, when I press and hold "A", my character jumps first (another, separate "A" function) and then I have to press and hold it again to get the upgrade.  Sometimes that precious time lost is fatal.
