Hi,
This happens when the clone or backup job fails and the snapshots are not automatically deleted. In this scenario the snapshots that were created during a clone or backup job remains with the VM. Any new data that is written to the VM is written on the snapshot file. Its important that you chose the latest snapshot file to maintain data consistency.
In your case you have multiple snapshots because you may have had failed backup or clone jobs in the past. You did the right thing while registering the vm but now I would consolidate the snapshots first and would then troubleshoot the failed clone issue.
