I am trying to create a custom weldment profile.

I have a profile that extrudes fine when i have designed it ( so i kno it should work), however once i try to bring it in to a drawing i get the message "Invalid member profile.Please check your library feature".Of course i checked it, with still no luck.Anyone got any ideas.I'm unsure as to what i'm doing wrong.In the profile there are 3 potential enclosed areas that can be extruded.I want to extrude outer profile only.I have tried inserting a gap (or a cut) so that the centre profiles do not extrude, then saving and trying it in weldements with no luck. I have saved it as a library feature ('L' displayed) and it is in the correct weldments folder. I have uploaded the design library file and photo.Any help will be great.

All i would like to do is create this custom weldment profile so i can use it in my designs.
