WWE2K14: Universe mode calendar always resets when I use a full roster of custom superstars?

[Xecution149]

I'm trying to play Universe mode with a roster of 40 superstars that are all custom. For some reason, every time I make a change to anything whether it be the calendar, superstars or options, the calendar resets, going back to the first Raw and the first matches. It doesn't do this if I only use a few custom superstars. Please help
