Back & OK Buttons are invisible in fileExporter-sheet

I use a .fileExporter-sheet to export some fles. In that view the save and the back button are invisible due they are rendered in white color of white background. That begins with iOS 15.0 and still remains with iOS 17.0.

Is there any way to modify the fileexporter-sheet ui?

Thanks in forward! Cheers!
