Incendiary shotgun burning damage does not count towards assault challenge

the "do 5,000 damage with incendiary shotgun" is only tracking direct impact damage and its happening 100% of the time. Any of the burning damage after you hit them, or the fire spots on the floor do not count towards the achievement. 

This achievement feels like **bleep** when the shotgun's main draw isn't even counting towards it. 

Please fix EA. Challenges in general were clearly created by ChatGPT and do not make sense
