Unfortunatly you are correct. Many of the components are user submitted and quality varies. The good thing is that they are available as source and can be fixed (although fixing or making parts isn't easy it is possible if we care to) and can then be replaced or used. As an example after reading this I cloned a copy of the lm386 part in core, looked at the schematic svg and determined the author had used a path for the two broken terminal elements (which is why it defaults to the middle of the pin element) and replaced them with more appropriate elements to create a corrected part. You can download and import the corrected part in to fritzing (where it will appear in your mine parts bin). You can then use it in place of the broken part in core to get a correct schematic. No need of another schematic package.
