Pre-populating Business Name on PDF

For the Moodboards, I like to add my professional logo to the bottom of the board. When I got to download the PDF, Design Files automatically add a box around my board and put my business name at the top in a basic font. It makes all the effort I did to add my style and logo to the board by adding this. I would love to be able to turn off this option and just let the PDF look exactly like how I designed the board.
