In Runway -> Configuration there is the option:
"Exclude vegetation around the runway"
It works in a project but does not work in the sim. The vegetation is always excluded in the sim, even if that option is disabled.
A similar thing happens with Aprons -> Exclude vegetation.
Whatever option is selected in a project (Exclude around, Exclude inside), while it does work when the project is open, it does not work in the sim (all vegetation is removed even if those two options are disabled).
