Actually these are two more general deficiencies. The one concerning the 
double rendering is tackled with the development version, see e.g.:
https://git.gnome.org/browse/dia/commit/?id=5978d9f58914198397cf353d0ff517cb6ae528b8

I've already optimized some of the exisiting shape files to avoid these - 
always unnecessary - double drawing elements. See e.g.:
https://git.gnome.org/browse/dia/commit/?id=4aad6da7502ade47817ba289b3e9650e913e097d 


But there are still a lot of shapes with Dia which would benefit from some 
proofreading and cleanup;)

The second one is the magic involved in custom shape editable line width 
with custom shapes. It has nothing to do with the renderer export (here 
shape export) but is a not fully documented convention in place since the 
introduction of the custom shape objects IIRC. See:
https://mail.gnome.org/archives/dia-list/2008-July/thread.html#00084

Adjusting custom shapes after export is always a good idea. But as I said 
not all shapes included with Dia got enough of it, yet.
