After installing Navigraph Navdata, most airports were marked with a custom scenery icon. This is a bit annoying because it makes it harder to figure out if it’s really a custom airport or not.
I found a little workaround for this “annoying” problem.
All you need to do is fix the manifest.json file
By changing the value of “creator” from “Navigraph” to “Asobo Studio” - custom scenery icons will disappear from all airports. And I can see again which airports I have custom. This changes is only affect to showing small subicon in world map.
P.S. So, as I have great respect for the Navigraph company - its name can be transferred to “manufacturer”: “Navigraph / Jeppesen”
P.S.S. Sorry for my google translate =\
