Weird Global Search Issue

I’m trying to add a new DAC to the global search.  The dac is part of an an ISV product.

I have customized the DAC with the following code, which seems to partially work, but it’s not displaying properly in the search results. 

After I run the rebuild Full Text process for this entity, I can see the data appears to look correct in the SearchIndex table, but it shows blank data in the Acumatica search results. (screenshots below)

Any Ideas?  Am I missing something?

Thanks

Scott
