Answer:
In CS2 (Stage 2) , diaphragm structure group were activated and it was not supported by anything. 
Hence, it is showing error as diaphragm is free to move.
Further, girder is not activated in this stage while girder group was activated. This means girder group was assigned properly.




So, add the the girder elements in Girder Group by selecting the girder elements> right click on girder group> assign plus as shown below.
