Wrong PrintDesigner Layout in Print-Preview

Hello Together!

Im new in ERPNext and I am trying to configure an Sales Invoice. Im using print-designer. I create a new Print-Format and in the Print-Preview the Format is wrong or the Elements seems to remove.

I did tweo Screenshots. Maybe you can help me. I’ve tried Chrome and Firefox without changes. Und i tried chrome or wkhtmltopdf. Both without changes.

Sorry for my bad English, i try my best! Hopefully you can Help me.

Kind Regards!
