Faction War and Crypt (Mortal Kombat X)

Mortal Kombat X Premium Edition Styam version, I can not change the faction, change while you are in it, you leave the game again you are in the same as you were, and every time you enter the game, it is highlighted that who won and you get a reward , and all the items that you bought in the crypt, while they are in the game, it is worth leaving all of them ... what's the problem? PC version. (if you need to try to make a video)
