Hello! Welcome to our forum!
This is currently expected and is part of our attempts to work around a limitation that came with MSFS2024. This limitation makes it impossible for us to set the order of our navigation data packages explicitly, which is causing issues for some users. We’re trying to find a solution by trial and error at the moment, which is why this product is still in beta!
We expect to be able to get rid of these odd filenames with the next cycle update. Sorry for the confusion!
Kind Regards,
Malte
