Gotcha. Yes, Map View should appear in the same order as List View at initial page load (it could be in a different order after searching by distance).
I see this event does have a venue/location but it still doesn’t show up in Map View.
Please send me a screenshot of this event’s wp-admin event edit screen as well as this venue’s wp-admin edit screen so I can see its details.
Also, are you able to replicate this issue with any other event? What about trying to recreate this event and just delete the one that doesn’t appear in Map View (if the 2nd-created one does)?
