XOA 6.1.3 Replication fails with "VTPM_MAX_AMOUNT_REACHED(1)"

[flakpyro]

Since updating to XOA 6.1.3 i have a VM that has secure boot enabled and will fail to replicate with the error:

"VTPM_MAX_AMOUNT_REACHED(1)"

Retrying the backup allows it to complete.

It appears to be trying to create a new TPM on the replica when one already exists?

Not sure why it fails during the job run but completes during a retry but it is consistent in its behaviour.
