Thank you for your report. The full address should be London NW9, England, United Kingdom, right?
I’ve tried to add this manually and it works (I compared it to the WP Grid Builder location and it seems to be the same). If you do it manually, does it work?
How do you have your ACF field configured? YOu can give a screenshot, so I can try with the same setup.
Here’s a screenshot of the ACF field - which is within a repeater (so that people can have several locations. There don’t seem to be any settings available other than the starting point shown to someone when they add a new location.
I can see the problem now. You can solve this by using Array value filter (Dynamic Data – Bricks Academy), so something like this should work: {acf_map_repeater_map_address:array_value|address}, just make sure to set the correct field name, just like in my case it is: acf_map_repeater_map_address, your is probably different.
I’ll mark this as a NO BUG, as it’s not a bug, just a different way of doing it
