Default airport show up after installing third party airport addon

I made an airport addon for Hangzhou Xiaoshan (ZSHC). The addon worked perfectly fine on initial version as well as SU1. However after installing SU2 beta I found that my airport addon was replaced by a default generated airport and I believe this correlates to a recent update on airport data in Mainland China area, because by default ZSHC was not existed in MSFS2020 and MSFS2024 older version.
In addition, when I open the project in Devmode, there is an error: “The airport should be in the same zone as the airport declared previously”.

Anyone has an idea how to solve this? The default airport is totally outdated.


The reference point of your airport should be identical to the base sim one, otherwise it can end up in a different QMID. I am not sure how to accomplish that in the scenery editor GUI for an already created airport; somebody else might know…
