Previewing game

I like most people updated to 9.3 and I noticed when previewing the game from start to finish vs. previewing a single level functions seem to not work.
For example; I created several levels that wind up at a bonus level. Once the bonus level is completed I've added a continue to next level button. It works fine when previewing just that level, but from start to finish it ceases to work. Any thoughts?
