I have seen this once before. The problem is the yellow model status light for the Ram Frame analysis.
This can happen if the steel beam or steel column design is skipped because the program thinks some of the member self-weights might be missing. Rerun those modules first, and then rerun the Frame Analysis so that the light goes green. Then, when you export to Ram Concept, the transfer loads should be there.
Make sure to include "Transfer gravity loads" and choose "Ram Frame" as the first source of those forces.
