No value is shown in PDF , only the table headers are shown

Hello guys,

i'm pretty new at drupal.
I installed this module and the libraries.
I made a display "PDF page" that is simular to the view i want to export as pdf. The view that i want to export is one table with some filter options.

But if i go to the PDF page link it only shows my table headers.
how can i link the values of my fields from my normal view to my PDF page ?

First i was using the "PDF Export" module , this module worked fine but i didnt had to show all my table columns. So thats the reason i need to use another module.

Can someone plz help me with this ? i'm a student and needs to get this done.

Ty very much guys!
