It looks to me like someone forgot to update the serial number on the zone 198.193.in-addr.arpa so your new delegation failed to propagate as it should have, The servers for 198.193.in-addr.arpa are: dns1.carnet.hr dns2.carnet.hr ns.ripe.net The first two know about the delegation for your zone 192/27.186.198.193.in-addr.arpa but ns.ripe.net does not. This is the cause of the inconsistencies that you observed. The SOA serial number for 198.193.in-addr.arpa is the same 2021052502 on all its nameservers.
