How to set up a map?

My friends would like to know how to properly set up a map in the editor. I created a new map, cooked it, and tried to access it through the game. However the map appears in the map list when I set up the game. But the name of my map appears several times in the list of maps of the game, as if each file of bioma, spawn, vegetation … were separate maps. How to solve this?

Here is a series of tutorials made by Exilog, designed to help people start out with mapping

When you are ready to cook a map, make sure that you only enter the name of your persistent level(the main level of your map) in the box, and then select “Cook Map”.

Many thanks friend, it worked!
