Floor load generation

Kindly refer to the model attached and reference pictures. 

For FLOOR LOADS created under REFERENCE LOADS I am getting "WARNING- NO MEMBERS LOADED FOR A FLOOR LOAD GENERATION."

However, in the GUI the same panel is indicated as loaded for the load I am getting the warning for. I am getting a total of 14 warnings. 

I don't know where I am mistaken.6011.Building 2.STDGUI indicating the Loading as per floor loadWarning given for floor load
