Every time I try to Enable custom domain

and click the Amazon siugnup button it says: "You already have access to Amazon Route 53"

So my main dashboard still says 89% complete with the last step being:  Add a custom domain

Clicking it just loops me to "You already have access to Amazon Route 53"

I don't have any route 53 domains. This is the first I've even heard of the service.

How can I Enable custom domain so that I can transfer name servers over?

thanks
