Render Elements PNG Error

Cmasking_Mask Render Elemen dont save correct with PNG Fromat

There is two images . One is VFB screen shot ( correct ) and die other is PNG ( incorrect )


what method do you use for saving? Is that an autosave, or do you save manually? From where? Corona vfb, max vfb, …? Can you screenshot the PNG settings dialog for me?
