Are you sure those column families are Structural Columns category and not Columns category?

Do you have other link overlapping with the current Revit model?

The Colour of the Yellow Columns is there but there is something over the top of it 

Visibility Graphics > Turn off any Revit or CAD links and check that the floor/ceiling/area is not hatched with a solid grey colour
