Traps rearming pressing space.

I disarmed a floor-trap with the disarming kit, it took one use and when I pressed spae to pick up the gem, my character re-armed the trap, so when I picked up the gem, the trap activated.

I am not 100% sure if this is a bug but it feels like something that shouldn't happen. Once a trap in disarmed it should stay disarmed, and reactivating it manually just seems dumb.

Am I the only one bothered about this?
