STAAD profile assignment to members.

I have assigned profiles to members, i.e. members 1 to 10 W8x15. I also designate material, elasticity content for W8x15. This syntax, when written in input, will show something like 1 to 10 W8x15. After I saved and closed the file, it should be this setting. But when I opened the file, the software detects that members were not assigned. Then it even assigned "....1 W8x15, 2 W8x15, 3 W8x15..." for a total of 10 profiles. Also, it even sends error messages that elasticity were not designated. Can someone provide information on why is this occurring to my STAAD file? Appreciate for any response.
