Did you check all the code? That's an example of replacement of RemoveWorldObject to RemoveBuildingForPlayer, there are no just Checkpoints but Spawnpoints, objects and so. What I wanted to show you with the code is how I did the replacement but it didn't work in-game, I mean, it didn't remove the world objects when you play the race. Check this part of the code of the Gamemode:

As you can see, to make work PickUps, Spawnpoints, Objects and Checkpoints with MTA codes which are located inside the .map file, there's a script code right there to make em work, what is missing is the code for RemoveWorldObject. I hope you got my point now xd.
