Supporters Gone Missing

I just noticed our random supporter blogs at tripawds.com have gone missing from the Supporters widget. Upon further investigation I discover the blogs are no longer Supporters!

We have v. 1.6.1 of the plugin installed. The plugin Admin "Statistics" list nothing next to Active Supporters. Attempts to extend Supporter status to the blog IDs does nothing. They do not become Supporters.

Any thoughts are welcome.
