HA out of sync since 7.2.10

[zexex]

since I've upgraded to 7.2.10 (7.2.9) before, my HA won't sync - since 14 days. Complained about the DNS-table and nothing helped, so I did a factoryreset on the secondary unit and configured the HA params only. Did a reboot and connected only the HA cables. This didn't help either, 30 tables out of sync (why???).

Did another factoryreset and used the same config as on the primary unit and changed only the hostname and the HA priority before that. Restored the config - HA out of sync, this time "only" rule.fmwp and firewall.internet-service-name. Rebooted many times, executed "diag sys ha checksum recalculate" on both units, nothing!

Fortinet, what have you done... Anybody else having such annoying sync-issues or and ideas how to get rid of it?

BTW, "exec update-now" on the secondary unit failed with code -6, so I connected the device to the internet (isolated) and did a "exec update-now". No errors there but still the same result...
