Hi,

You can change the paper format of survey certification to fix this. For that : 

1) Go to settings.
2) Activate the developer mode from the settings page.
3) No you will find new options added in the menu select "Technical" from that option.
4) Select the "Paper Format" option from that(under Reporting).
5) There you will find "Survey Certification" click on it.
6) You will find an option "Paper size" in it. There you can select your correct paper size.
