Hi, I am having a problem getting this achievement on the Xbox One, I currently have 89/90 Mission Specific Assault Ops Complete. The sidearm slaughter for me is 1089/50 which seems to be glitched and was not counted for completion. Please help me as soon as possible, Thanks.

Also, I am running off of the Games with gold for Spartan Assault.
