Hi,
Based on the picture the default ARCHICAD library parts show the 3D axonometry fine, and the 3rd party "Single Robe Hook 1" Library Parts are the ones that don't.
This tells me that it is probably an error in the code of those library parts (probably in the Master Script and/or the 3D script), so you should contact the developers of those library parts about this.
