Trouble in exporting Marketplace data error: Unlisted file found in source directory. (sim.cfg) of a jetway

Hello, i am having difficulties in makeing the Marketplace Data. it is unable to compile due to [Build Marketplace data error: Unlisted file found in source directory]. it is related to Landmarks SimObject Jetway. is there any thing that i could do to rectify this and make the export possible. thank you

I have the same problem here, a package that has last submitted to the marketplace in September 2023, cannot be exported anymore, because the sim fails to build the marketplace data with these errors:

Unlisted file 'C:\umberto\kclt\Dev_files\MSFS\FSDT_KCLT\PackageSources\SimObjects\Misc\fsdreamteam-kclt\sim.cfg' found in source directory

Unlisted file 'C:\umberto\kclt\Dev_files\MSFS\FSDT_KCLT\PackageSources\SimObjects\Landmarks\Jetways\sim.cfg' found in source directory

According to the documentation, sim.cfg files for Simobjects should not be added as Extra, so why the error ?
