Unable to add index from tribe node

Greetings!

I currently have two ES clusters and a tribe node connecting them. I am attempting to add an index from each cluster and am having trouble. The first index, which uses the default 'logstash-' pattern, is found and added. The second uses 'udplog-' and it says that it is 'Unable to fetch mapping' and the button is greyed out.

The tribe node appears to be configured and working correctly. I see both indices and can query each independently. What's could I be missing?

Versions:
kibana - 4.4.2
elasticsearch - 2.2.1

Of course, I found the issue immediately after posting this. It was PEBKAC. I don't see how to remove this post.

Providing the solution may help others in the future if you don't mind sharing.
