Starting Roster Not Saving

[washamur]

I'm in the finals with the Spurs and have been starting Boris Diaw at center for most of the playoffs. I've decided to start Splitter back at center for a better sizing matchup. Every time I go in and make changes, then go to start a game ... it is still showing Diaw as the starter. I go back into my roster and it's back to the old way. I'm making changes, but for some reason it isn't saving before going into the game. How do I fix this?
