2nd CPT Appears in Appearanc->Menu list, but not the first CPT

Hello, GeoDirectory –

I started my site with a single post type (Businesses). Later I added the CPT add-on, and introduced a 2nd post type (Groups).

I went to update my site’s primary navigation, so that a user could quickly link to whichever of the two post types they wanted to explore.

On the Edit Menu tab (Appearance -> Menus -> Edit Menus Tab) I saw that there was an entry that would allow me to choose my new CPT (Groups) and add it to the menu structure. Or add any of the individual groups to the menu structure.

But I was surprised to see that there was NOT an option to add the original post type to the menu.

I was able to work around it by creating a custom link, but it seems like a bug that it wasn’t there automatically.
