High availability with rspamd - no synchronization

[Wuensch-AG-Adm]

Hi there,
we currently have two new opnsense DEC3860 with the enterprise edition which we want to use as e-mail appliance.
We implemented rspamd in High availability with the help of this documentation:
https://docs.opnsense.org/development/backend/legacy.html#xmlrpc-ha-sync
(the same goes for clamav and redis)
We manually set the synchronization for rspamd.
Most plugins we can use in high availability, but with rspamd we cant get a synchronization.
We really need this synchronization since we use it for a failover.
If someone has any idea, why it isnt synchronizing then please share your experience with us.
Thanks in Advance
WAG Admin

You mean there is no config sync like within postfix?

no there's the config (please see the screen shot, but it does nothing when it sync either manually or with the Cron job :-(
