Diamond can't get Gears of War 3 skins to stick

Hi old member here, with the release of backwards compatibility I have renewed my diamond subscription in order to get skins I had lost in the recent years, mostly due to new account. I can’t seem to get the skins to stick now when playing the game. I can get weapon skins to work fine, but specifically character skins for locust and COG are no longer working. Anyone else have this problem? if so how did you fix it?

No I am not going to options to check, and I am not switching characters before starting a game, just loading up as “marcus” or “drone” :confused:

Are they DLC ? if so you cant but other than that you should be able to use them i can give you my personal save if you want its only reup 1 with all skins
