Please download the "Leaflet-Patch.zip (67.8 KB) " folder.
Go to the location “C:\Program Files\Helical Insight\hi\apache-tomcat-7\webapps\hi-ee”. Path might be slightly different based on the server on which you have done the installation.
In this location there are folders by the name of “JS” and “CSS”. That folder is to be replaced with folder “JS” and “CSS” which you will get by extracting the zip which I am sharing with you.
Then try in a private window and the maps will work fine.
Let me know in case of any other questions.
