I just updated to all the Apr 19 releases on my dev environment. I am using latest WP and most wpGeodirectory plugins. I use the Listing Map (gd-home) and use the CPT display across the bottom as the menu to pick which CPTs to display (I have 4 CPT).
In this case, one of the CPTs is Events. Currently I have no Events loaded that are in “upcoming” times. When I picked Events in the menu at bottom of the listing map it correctly said ‘no events’ available. However I then could not pick any of the other 3 CPT menu items. It was stuck on events.
To try to clear it, I then went back in to Admin and changed the date of an old event to a newer date so it is ‘upcoming’. After refresh, this cleared the problem so that this one event displayed and the other menu items were accessible.
So it seems the problem is, if the Events search (triggered by clicking on the CPT bottom menu) returns no results, it would not allow selection of other CPTs on the map menu.
