Am running MacOS Ventura and when exporting flight plans from Charts to many Export types a .pln gets added to the file name, for example if exporting to a JARDesign Airbus, I get something like KLASKSEA.txt.pln. This happens with most .txt types, as well as the iFly export types. As well, if I try to remove the .pln in the file dialog popup, it won’t let me.
Whoops thought I had done a proper search for the issue before posting, missed this one. Thanks for the quick response, not a biggie, the export still works fine.
