What does this warning mean?

**WARNING- Castellated beam 7 has force/moment in FX, FZ, MX and My direction. It cannot be designed 

Design of a castellated beam is done only for FY (shear along the web) and MZ (moment about the major axis which is the Z axis). If at the start of the design process, the program detects that the beam has axial force (FX), shear along local-Z (FZ), torsion (MX) or moment about the minor axis (MY), design of that member will be terminated.
