Duplicate Syncs

I am using a 67i, if I sync it using the iPhone app, and then I plug it in to the computer it will also sync using express. I think the same behavior happens if it connects to the wifi and then I plug it into the computer. I offend have duplicate data in connect.  

If I tell express not to sync the data, that setting flows to all methods of syncing. Is there a way only to have the device sync to Garmin Connect once? Thanks Mike
