Table with the custom DAC alias cannot be found in generic inquiry

I’ve created a custom SQL table and DAC, but having difficulty using the new class in a GI.  

This is the error when referencing any of the fields:

Also, when trying to specify the new GI on the navigation tab of a different generic inquiry the [Item] parameter is not available as a filter, and none of the fields appear in the dropdown either.

The custom DAC is available to select on the Tables tab of the Generic Inquiry, and the Alias seems to match:

The GI runs and filters correctly, but we would like to use it as a side panel on another GI and that won’t work because the navigation parameter isn’t available.  I have tried republishing the customization and restarting the application several times.

The GI returns data when run on its own:

Can any customization gurus out there see what might be wrong here, or set me on the right course on how to troubleshoot this?

Thanks in advance!
