Can only use one save. walking dead xbox
So yesterday i purchased episode four amd completed it. I have two saves and decided to play the other one, whis is game save 1. When i click game save 1 it goes to the 5th episode on the choose episode screen and says coming soon. So i go back to episode for and it says continue. Shouldnt say that considering i havent even started episode 4 on that say. So i go back and game save 2 is highlighted instead of three. When i continue it just goes to the end of episode 4. So basically i cant use save 1. Much to my dismay i delete both saves and start a new on on game save 1. I play for a bit then decided to get off. I just came back and now.its on game save 2! I cant even start a new game on the other saves either! Can somebody tell me whats going on here? Sorey for the lengthy question. Thanks.
