ZPL problem with layout A5 landscape

The data in my ZPL is not complete. I generate ZPL using GeneratePrintedOutput2. I use the zpl300.xdc.

The XDP size is DIN A5 page orientation is landscape. When I switch it to page orientation = portait the data is complete. Does Adobe ZPL not work with XDP-layouts using size DIN A5 (height 148mm x width 210mm) and page orientation = landscape? Can it be fixed by changing the XDC ?
