[Fixed] Cant change Package name


I edited an airport scenery I build a year ago. Now when building the scenery I get an error due to the Package Name.
The actual problem is now, that I can’t change the Package name. Whatever I try, everything I type in the field gets immediately deleted/changed back to prior name. I have no chance to change the name.

Does anyone know how I can fix this?


EDIT: I fixed this by changing the packagename manually in the specific *.xmls.
