While designing beams of a group a floor together for a multi-story building, the software error. There is no problem if I design for each floor level separately. 

There are some missing beams marked in snap below. Please note that the levels can be grouped only if the beam arrangement is similar at all floors. As RCDC is design and detailing software, it generates the Beam elevation. If the Beam are not same at all grouped levels, then it would not be possible to perform the beam design and generate the design calculation reports including drawings.
