Rebaseline of DP volumes not happening during fallback

We recently performed a Failover/Fallback activity (Work Load Swap) for User CIFS shares.

On Failover, we broke the mirror from DR & resynced from Source. So the source becomes DR & DR becomes source.

On Fallback, We tried to resync it from DR as it was before.

Resync not happening for the volumes with the following error messages:

1. The Destination volume must be DP (it became RW once the snapmirror was broken during failover)

2. No common snapshots exist between Source & DR Volumes

Is deleting the old DP volume & recreating a new one with the same one, the only solution for this? Or is there an alternative for this.
