This is a case where it was easier to fix the problem and then tell you what I did. Schematic here is the main problem (although there are others as well):
schematic:
group id g7 to id schematic to set the correct layer name
Adjust the alignment of the pins to be on a .1 inch grid and reduce the font size to 3.5 to fit the characters correctly (few words for quite a few changes 
).
bb
group id g7 to id breadboard to set the correct layer name. The only problem I know that this causes is that the part won't export as an svg without the correct layer names. Last edited all 4 svg files to remove the px from font-sizes that Inkscape adds (you may not need to do this if you don't use Inkscape) . The problem this causes is after editing the part in parts editor it will set the font size to 0 and your text becomes unreadable if the px is in the font-size. If you can't figure out what I've done feel free to ask and I'll try and explain. As well note the
"_1" on the end of the fzpz file name to indicate a different version of the part.
