Can't remove i13 Partial poses from Smart Content

Muneman

A bunch of these partial poses show up in the Poses > By Function categories, which makes it very difficult to sort through my poses because of how many there are. I like keeping them just in the By Region categories for when I want to do fine tuning. But when I go into Categorize and remove them from the By Function categories, they don't get removed. Some do, but not all. Is there a way to get around this?

I do use the Genesis 3 to Genesis 8 Pose Converter, but from what I can tell this is happening with the original versions and not the conversions I've made.
