Duplicate records being created on iPad (Spoke) after creating single record on Hub (FMS)

[Crawfcol]

We are relatively new to MirrorSync (6.12).  We can have a system which is syncing with no issues.  We create a new record on the FMS in a table that is synced to the Spoke (iPad).  After the iPad syncs and receives the new record, the next time the iPad tries to sync, they receive an error that there is a Duplicate ID...  

On researching the issue, whenever we create a single record on the Hub, 2 records with the same ID are created on the Spoke with the same ID.

This effectively breaks the sync and needs remediation by the user of the iPad by the deletion of one of the records.
