Error: can't find "option" attribute

Dear STKO team, can you tell me how to deal with the problem as following.

It seems you are using directly a Section physicalPropery with a disp(or force)Beam Column element.
You should instead use a BeamSectionProperty (as a physical property), where you specify both the section and integration scheme
