Problem displaying the google maps widget

Hello, we have a problem, we are trying to create a map to place points using the google maps widget.  The coordinates come from a postgresSQL database. The map is displayed correctly and if we enter the coordinates manually everything works. And the data that comes from the database is correct because it is also displayed as you can see on the picture. We have recreated the widget several times without success. If anyone has a solution or an idea, we'd love to hear it. Thank you very much for your help.   mendix version : 9.22
