Supporter problem - blog disconnecting from profile when extended


I'm finding that when I login as Admin and extend a Blog (activating them as a Supporter),
their blog seems to disconnect from their Buddypress profile.

First, here's the site:

Here's an example:
In this member's profile, there are 2 blogs listed. Both were accessible from her profile:

Then, after I logged in as admin and extended one of them so it could access the premium plugins, it is no longer accessible from her profile:

You can see here that it is no longer listed:

How can I stop this from happening?

How can I reconnect this blog to it's owners profile?

Thanks, Derek
