Additional Poller issues

Let me preface this question by saying that I am new to Solarwinds and the Thwack community.  I will be attending training next week so forgive me if this is a dumb question.

I have NPM/NTA/NCM and UDT installed on my network.  I have the main polling engine and three additional pollers.  My issue I am having is that the main poller works with no issues.  My additional pollers poll and the node but I am not seeing any activity on the interfaces I have marked for monitoring.

Ex.

The node (router) is up and I see the interfaces but I am trying to see stats on the serial 0/0 interface and nothing is showing up.  When I move that router to the main polling engine, stats start to appear.
