You should download the free version of REDitor. When I loaded your file, some of the names were missing. I'm going to load it in REDitor, then copy and paste the contract changes to my roster. It'll be glitch free, or at least should be.
If you don't mind doing draft classes, I would ask that you just do the fictional ones. I don't really care about real names, I just want draft classes that fit the ratings and tendency scales in the roster already so future years of associations aren't completely ruined.
