airport lost in little nav map

Today I tried to do a flight between zswx and zsyt on China, but in lnm zsyt is red. I controlled, but the airport existes on msfs2020, and using airport design editor, the airport is complete, why?

Does the airport use digital rights protection (i.e. encrypted)? If so, LNM can't read it. There are a number of posts about this here.

Negative, there are, on real two airports with the same icao, one is Penglai ( civil airport), other is Laishan ( military airport)

This might be the reason. LNM does not allow more than one airport with the same ICAO id. One will erase the other.

Actually this looks more like a scenery error since the BGL format cannot deal with duplicates either.

You can exclude the BGL file of Penglai in LNM options if you don't need it.
