Design library features not recognizing in .dxf layer entity map?

Hello all,

This post is in reference to CNC routed sheet metal parts. I am attempting to push different geometric features to different .dxf layers during export, however, as SolidWorks doesn't seem to allow individual feature selection in the part tree, I am trying to use the design library to work around this, as SolidWorks seems to have the ability to export design library features separately. My issue is, the library features option isn't being recognized/does not come up as a mapping option, even though the part contains design library features. 

The attached pictures show what I'm seeing, and for reference, the smallest holes on the left are the design library feature, and that feature has been patterned. I've tried it without the pattern, no change. Any advice would be greatly appreciated!
