RCDC: Analysis from RAM SS, beams missing, columns missing

I want to design the concrete part of my structure using STAAD RCDC however after selecting the RSS file, RCDC says beam are missing and when I run the column design to it says that columns are missing. Any Idea how to fix this issue? It will be very beneficial to my work. Thank you very much.

I will attach photos for reference and will be happy to send the RSS file if necessary.
