co-op achievements didn't trigger

My sister and I Just completed the campaign for Gears of War Ultimate edition co-op style. I was awarded the A dish best served cold, Mercenary and I Can't quit you Dom achievements but my sister (who was logged in under her profile and had been getting the achievements the same as me) Didn't get those three. It is said that it didn't matter who killed RAAM to complete, and her achievements have them listed with 100% progress but the score was not added to her gamerscore, and the images for those are still darkened out and locked. how can we get them to trigger and be added?
