Scenery missing when adjusting settings iniManager

[GentleMolasses]

Airport ran fine in MSFS 2024 after first install, however, whenever I adjust the scenery settings in the iniManager, for example turning off "Static Aircraft", MSFS 2024 only shows the default scenery.

Reverting the scenery settings in the iniManager does not resolve the issue, I have to do a complete reinstall of the scenery. The default scenery is also disabled in the marketplace settings and I only adjust the scenery settings in the iniManager when the game is not running.

Any ideas what's going on?
