Railway Stations Not Rendering Walls#565

Currently I’m in the Roermond Railway Station and there are ghost walls (no wall visible but i know what it’s supposed to look like in here). This has happened at other stations. The station is in it’s damaged mode. I’m not sure if it happens when it is all fixed up. The last railway station this happened with I could see out all of exterior the walls but of course nobody could see in.

If you press the rt mouse button, they all appear

Yes, the walls appear when you right click.
