Syncing saved destinations to car erases them from phone?

Recently, I saved several destinations in the Entune app and called them up on the MFD, which prompted me to sync the car to the phone app. I did that and all the destinations appeared on the MFD. But I later found they had all been erased from the phone app. Is this normal behavior? Thanks.

 

Yeah, that's just part of the odd behavior. After the first time all were erased from the phone, I recreated a couple (on the phone) and then, ahem, "synced" again with the car. Again, the car deleted them from the phone and created duplicate entries on the MFD.

Related frustrating issue: After all this, I thought, "Well, I'll just edit the items on the MFD" (delete the duplicate entries, maybe rename a couple), and found that the only edit function is an all or nothing delete (the trash icon at top of screen). I really hate half-nice person programming....
