DNS sync between 2 active-standby bigip load banalcers

Hello Anime, 

But I have found something new when read the document:

https://support.f5.com/csp/article/K13690

I Found that when run tmsh show /gtm iquery , it is not reporting BIGIP-DNS but just BIGIP

[root@LB1:Active:In Sync] config # tmsh show /gtm iquery

I then try to create a new Prober Pool and put them in, and it seems that makes some progress

However it still shows as BIGIP and the DNS still not sync, I am not sure how to fix it, would you please advise how should i fix it so that it can report as BIGIP-DNS when run  tmsh show /gtm iquery?

Thanks
