Conquest glitch

I had this glitch in conquest when I was using my slkr team with hux, hux in particular would just lose health bars (not getting damaged), but  its not like his health would go down it would be full but there would only be 3 or 4 sometimes even 1 health bars at some point in the battle and he would obviously die and it would cost me  a keycard he also does the same amount of damage only his health is effected.
