Today's workouts synced with MFP, then disappeared from watch and Garmin Connect?

I used my Forerunner 15 to record a run and an aerobics workout today. I came home and hooked it up to my computer. When I logged into My Fitness Pal, it had synced and added the calories burned to my daily goal. However, when I logged into Garmin Connect, today's workouts weren't recorded. So I tried to import them manually, but they are no longer saved on the watch. I know they were there. I checked them some time after the workouts to see how many calories I had burned. When I plugged the watch in they uploaded to My Fitness Pal. Where did they go after that? When I try to look them up using the history button on the watch, they aren't there, either. The last workout is shows me is last Friday, so Sunday and Monday's workouts have disappeared, too.
