Re-rolled 'Get 50 kills or assists as Engineer' not tracking

Your task is for recon class, check your icon. There is just mistake in caption i guess. Anyway i have correct class icon and its not counting. :( 

I'm having the same issue. Rerolled a different challenge and still not getting kills.

Tried switching to Recon although the icon is correct for Engineer

So in the last couple hours I've tried running all 4 classes to see if any of them give credit and none of them are. Guess it's impossible to complete this.

good spot, that seems to be tracking correct under recon. but i could've sworn i played recon earlier in the week on breakthrough, though, just to get no progress. hope it fixes for you guys too.

only thing i could really suggest is trying different modes, or maybe switching from one class to another mid-match? because i did my dailies first and switched from support to recon halfway through a match today, no idea if that's anything to do with it unfortunately tho.

I did the same thing. Rerolled a BR challenge I'll never do and got get 80 kills as engineer. It shows the recon icon, but I tried all 4 classes and none of them counted for the challenge...

You need to play as recon. And. You have get kills with c4 on tanks  I had the same problem
