I have added a simple location field in my article content type, and enabled the location block to be shown in main content type.
During the creation of an article, when I enter the location values as text fields (e.g. countries, cities) without any latitude and longitudes, the map is not displayed on the article node page.
However, if I do enter some latitude and longitude values, either manually or using Google Maps, then the map is shown in the article node.
Does anybody have any idea why this happens?
