Description of problem:

After running an OADP backup with multiple PVCs, one PVC will show "Snapshot Size (bytes): 0". The PVC definitely has data and the data has been changed since the last snapshot.

Version-Release number of selected component (if applicable):

OADP 1.4.2

How reproducible:

So far, only reproducible in the CU environment

Actual results:

Some snapshots appear correctly, but one PVC shows the wrong size.

Expected results:

All PVC snapshots should show the real size.

Additional info:
No errors are encountered during the backup and the 0-byte snapshot shows a status of "Complete"
