Problems with mapping objects on Server

[Stromsan]

Good evening. I have a problem that mapped things like a hotel room or similar with me on the server not shown. becomes. 
I once tried Menyoo and Map Editor including Mapbuilder. 
Do I have to install an extension on the server for these props to be displayed correctly? 
I've been looking for a solution for 7 days now, but I can not get any further. 
I would be very grateful for a helpful answer. greetings
Also in private chat, it should go beyond the scope
