Railworks America

Downloaded and installed Golden Age of Rails BN and SLSF gondolas. Also downloaded and installed the shared asset file. Have Great Northerner GNry checked off in the editor.
When I go to place these cars on the track nothing comes up. Reinstalled and still the same. Anyone got any ideas on how to fix this?

Are the Geo files in the folder for each of these?

All the Geo's are in place for default, BN, NP and SLSF.
