Unable to map 2 domains to site on multisite

exitrealtyatlantic.com
exitrealtyatlantic.ca

These two domains have fully propagated are pointing to my multisite however I cannot map them in the subsite.

As a test I tried another domain i have: findanagent.ca and that one I was able to map with no problems...

I must of messed up somewhere along the way but can't figure out where... Any suggestions?
