L26 might be bugged

I feel like the British L26 APFSDS might be broken. Recently I’ve played the Challenger DS a lot and the L26 seems to do near to no damage (images below). The dart itself does damage, but the spall from it does near to no damage so it usually takes me 2-3 shots to kill 1 tank because I need to shoot the crew individually with the dart. This is against every tank and from every angle. Not sure if it’s a bug or if it’s just that bad which I doubt.
