Contribute 2 Source Code

When updating our Contribute 2 page from our last development event I ran into an issue with overriding the source code number. I've updated the system tables and updated the TNEW page. But when someone goes online to purchase their ticket the order is coming through as a "General Website source (the default) and not the desired Nutcracker Ball event source. I have listed the correct fund name on the TNEW_CONTRIB_TYPE and am not finding anything on the TNEW Admin page about overriding a source code for the Contribute pages. 

Is there something that I'm missing?
