ACME certificates not syncing with backup node

[sshami]

Hi gentlemen out there,
I have setup for Pfsense in HA/SYNC cluster mode (Master and Backup) with CARP vrrp configured.
Sync is working fine with HAProx and others like FW rules, it we create a rule on Master node HAProxy like fronted and it immediately replicate to backup node, this is fine as expected.
But when comes to ACME certificate, after creating on Master it's not replicating to Backup automatically and i see nothing on backup side.

If i go to Master node and see System > High Avail. sync > Select options to sync > Certificate option is checked already.

On both nodes HAProxy and ACME packages are installed!

Thanks in advance!
