Nothing shows up in airport customization window

[kannagi]

I cannot select any parking location in this window and can’t create my own .ini file. I was able to download other people’s profile and it works fine if I drop them into the GSX msfs folder, but still, nothing shows up in the window on the left.

When I tried downloading other people's profile and dragging them into the folder, it is recognized by GSX but still, no option to customize position.

SU10 navdata API is enabled in the option but still the same result.

In the Windows regional setting, set the option "Language used for non-Unicode applications" to English.
