If you're referring to the WikiTree Cemetery Maps app that Steven Harris just provided us, it's not showing up because the Category InfoBox does not include the GPS coordinates (only obvious when you Edit the page)

I added this one, but to fix it you would simply click on the link to the FindAGrave map, coordinates are top right, and you can copy/paste into the Edit page under the Coordinate = space.
I think Steven said Ales updates that info once a week, so it may be a week or so until it shows up, but it should soon.
