I've got an "Author" role that a subscriber gets put  into after successful payment.

Now I want to show all authors something like "Hello [FULLNAME] ... you are now an "author" on this site ... thanks for subscribing!"

And I want to show all (DNN) Registered Users something like "Hello [FULLNAME], please consider subscribing, which comes with the following benefits ...!"

In my tests the Registered User message will show for Registered Users AND for users with a valid subscripion (users who are in the Author role.)

It only shows the message for Authors if I clear the content for Registered Users.

So how does it determine what message to show if a given user account belongs to two roles? What am I missing?
