Have been looking at the MARC to MODS mapping document lately, and noticed that you have

245 $n (and $f$g$h$k following $n)      mapped to    <partNumber>
245 $p (and $f$g$h$k following $p)      mapped to    <partName>

Shouldn't subfield h (medium, a.k.a GMD) only be mapped to <form authority="gmd">, not to <partNumber> or <partName> ? 

Am thinking the stylesheet doesn't actually map $h, or $f,$g or $k for that matter, to either <partNumber> or <partName>, unless I'm missing something.
