PalmTree and stuff in the air

Hello.!
I have bought this plugin and follow the first setup video for the Bankheist.

But when i have finish the ground around the bank and have set up the roads to the bank and saving the bank as in the description of the video in RustEdit.

But when i load it in the server, then it has spawned a lot of Palm trees and bushes and stones around and in the bank as a flying objects, and how many times i try to start over and fix that problem, it comes up the same every time, What do wrong "or" What have i missed to get this flying trees and other stuff appear when i load it in the server..?
