Progression - Challenges

I already have an open bug on Challenges - Class - Engineer #3 where I completed but am stuck on (deal damage to aircraft) with 1840/2500 and now ironically had 1/3 challenges - class - recon #3 (headshot kills beyond 125m), I just scored two more to complete that task and see now that I have 0/3.   Very frustrating !! Please fix and give credit so I can complete these.
