Not picking up all custom post types

I’m trying to connect this with the “Tribe Events Calendar” plugin.. It sees the CPT called “Events” (tribe_event), but it doesn’t see the CPT called “Venues” (tribe_venue). I also tried manually adding it into CPT UI, with no luck. Any ideas?

Also, when you populate a dropdown with a Custom Post Type.. The result is the Title of the post, or the ID? I’m trying to specifically get the ID.
