How to remove a morph category from panel?

I imported some custom morphs. I changed the Drivers from "Rig" to "Mesh" to see what it does and it created a separate Morphs category called "Mesh Shape Keys" in the DAZ Runtime (version 5.1.0.2859) panel. Going to the DAZ Setup panel, I couldn't find a way to delete the category in the "Mesh" category because the option to remove it was greyed out. I was able to find the shape keys and custom properties and remove them, but I couln't figure out how to remove the category.

How do I remove the morph category I created, "MD Body Joint Bends" from the panel?
