Scenery Library Builder does not recognise some third-party airports in MSFS

Hello, I've noticed this issue earlier but I wasn't certain it was an issue with the program until after I updated to SU7. After updating to SU6 and Little NavMap to version 2.6.17 in October, I've noticed that the scenery library builder is not marking all of my third party add-on airports with a yellow outline, for example KDCA https://flightsim.to/file/1071/kdca-ronald-reagan-washington-national-airport meanwhile nearby KIAD by the same author https://flightsim.to/file/1113/kiad-washington-dulles-international-airport is marked as expected. This is also present in some other airports by other authors like CYUL https://flightsim.to/file/1691/cyul-montreal and CYQX https://flightsim.to/file/6912/cyqx-gander. I tried this with both the stock Navigraph database enabled and disabled. Building the scenery library in v2.6.16 recognises the add-on airports as expected.

Thank you for the detailed report. Looks like a duplicate for #798 but I keep it for the examples. Will try to fix for 2.8.

Tried all three airport add-ons with 2.7.9.develop and these are recognized now, no matter if Navigraph is installed or not.
