Regarding version, FREEDOM-FOR-Icinga repository seems, it was my mistake, after checking we are using packets from original Icinga repositories:
[root@icinga yum.repos.d]# yum info icinga2

Description : Meta package for Icinga 2 Core, DB IDO and Web.
version installed and used is 2.14.3. I am informed that it might pose security risk, although currently migrating to newer version of Icinga (new backend) would propose problems regarding visualisation, since we use nagvis which is not compatible with new Icinga and it stopped releasing in 2017.
I did try also reset of icinga-director service, which seemed to help. But it seems to be bugged. Hopefully they would patch Icinga also for Centos8/Almalinux8/9.
