This means the maps builder has assigned the set up to the map in order to not having to reset them all again when a new session is created. If you wish to change them delete the code in the top window of the assets properties window. Close and reopen to do the changes. If you want to keep the new changes to the route you will have to copy the code exactly as shown in the top left of the properties window into the name window at the top. If you don't, the next time you start a new session the set up will have returned to the default setting as if it was a new asset.
