Replication error with renamed pool

[HugoMcKinley]

Hi,
i have a problem with the replication of a Jail.

I renamed a jail from FHEM to FHEM_ALT an another jail from FHEM_NEU to FHEM. (New install of a jail)
So the storage pool of the jail also got renamed without any problem.

At the next replication of the jails i got the following error:

Code:

* Replication "HTL Offsitebackup" failed: send from @auto-2020-03-20_23-30-5w to M2TB/iocage/jails/FHEM@auto-2020-03-21_23-30-5w estimated size is 30.6K
send from @auto-2020-03-20_23-30-5w to M2TB/iocage/jails/FHEM@auto-2020-03-21_23-30-5w estimated size is 30.6K
cannot receive incremental stream: most recent snapshot of Backup/iocage/jails/FHEM does not
match incremental source..

Solution was to delete the target pool and replicate the data.

I know why this happend, but shouldn't this be corrected automatically when Replicate from scratch if incremental is not possible is checked?

Is this behavior intended or is it a "bug"? Or in other words, what was my failure?

Greetings,
Hugo
