Did not start 2nd half with a kickoff

I ran a final play on 4th and 2 with 2 seconds left in the 2nd quarter.  The play ended with zero time left and an incomplete pass.  The opposing team was slated to recieve the 2nd half kickoff.  My Dynasty game is set to play offense only, so when the game switched to sim for defense, it gave the opposition the ball at the line of scrimmage of my previous 4th and 2 play, even though it was the end of half and should have been a kickoff.
