Replication error.... or not?

[Jawloms]

Both my DCs are 2016.

 

If I type repadmin /showrepl on server1, all is reported fine. If I type the same on server2 I get this;

Did some Googling and found a Technet article (here) which said to replicate just the bit with the problem so I did by doing "repadmin /replicate $server1 $server2 CN=Schema,CN=Configuration,DC=$domain,DC=internal" and "repadmin /replicate $server1 $server2 dc=ForestDnsZones,DC=$domain,DC=internal" and both worked fine. Tried the same commands but switched the source and destination servers and all was still fine. So do I have a problem or not, and if so, where/what is it?

And nevermind cos it seems fine now despite me not doing anything.
