Unreal Engine Source Control Map Problem

Hello, to begin I apologize in advance if my English is not very good because I’m French ^^ ’

So here is my problem and I recently learned to use the source control via a video, for that I use “Tortoise SVN” and “Dropbox” so I put the file of my game and followed all the manipulations to do but when I do the manipulation on another pc I have all the files in the game except that the map is not the right one is the one when creating or new project blank with the starter content … I do not know how to fix this problem …
