For some reason, after I subscribed to the devtools rpms located here

https://developers.redhat.com/products/devsuite/hello-world/#fndtn-rhel

by

# subscription-manager repos --enable rhel-7-server-devtools-rpms

I get an error in subscription-manager stating that my Red Hat Developer Tools are not supported by a valid subscription. Although, I know that I have a current subscription to the free developer program. Anyone have a clue as to why I am having this problem? All of my other subscriptions are up to date, e.g. software collections. Here is my output of
