GTM doesn't seem to resolve its own WIP

Hello,   So I've spun up a new GTM (11.2.1) and there are two LTM's (each at different datacenters). I've created the VIPs (test.company.com) on the LTM's and a WIP (test.gtm.company.com) on the ...

The pools are behind the LTM and are inherited by the GTM, hence the GTM is doing inter-datacenter load balancing. The GTM big3d dameon is reporting the pools green. I believe the problem is something with DNS in that the GTM doesn't query the WIP name...perhaps because maybe it's not authoritative or whatnot?

 

Configs:

 

gtm wideip /Common/test.qgtm.company.com { pools { /Common/test.company.com { order 0 }

 

gtm pool /Common/test.company.com { alternate-mode global-availability fallback-ipv4 any fallback-mode none members { /Common/dc1ltm01q_dc1ltm02q:/Common/test_company_com-443 { order 0 } /Common/dc2nltm01q_dc2ltm02q:/Common/test_company_com-443 { order 1 }
