Using Webform (7.x-4.15) with BerryPro

Hello,
I use Webform 7.x-4.15, webform conditional and webform rules and I would like to remove author information.
I read in several forums the following suggestion : unchecking display author and date information into structure>content-types>webforms but I cannot find the field to uncheck.
Does Berrypro change the way of removing author and date information ?
Thanking you in advance,
Best regards,
Corinne
