I just noticed that I had not claimed the rewards that I earned running the various "Round" events. I guess I didn't realize that they could still be claimed even after the round had ended. I lost some that were available from Rounds 1 &2.
Go to this screen and you will know immediately if you have any unclaimed rewards:
