Personally I use a geolocation field: https://docs.metabox.io/extensions/meta-box-geolocation/ With as map: Open Street Maps. So if your marker is ok in your backoffice form AND you refer to the map display field (https://docs.metabox.io/fields/osm/) when you set up your "map facet" in grid builder, this should to walk.

Hello, To solve this problem with markers, I directly mapped the "map" field and not the "lattitude" and "longitude" fields.
Hello, I am facing the same problem. however I did not understand how to implement your solution. Could you enlighten me on the steps to achieve this?
Best.
