How do you uninstall a scenery in P3D ONLY?

[Papagiorgio]

I installed several airports in P3D v4.3.  When I look at the scenery library in the sim, they're all active, but they are greyed out so I can't uncheck then, edit, or delete them.  I have FSX-SE installed also, I don't want to delete them there. I found that if I add a scenery directly from P3D, since I already have the files, it installs properly so that I can select it or deselect it.

You can disable an add-on from P3D3 ( it only works in P3D 3.4 ) from the Options->Add-ons menu.
