I recently bought a PLR. I edited it a little to change it and want to sell it in my Stan store. I have a free canva account. Upon trying to download my edited version of it as a PDF standard in Canva, I get a message "Your Design contains premium content" and need to upgrade to Pro. I only changed or added a couple of backgrounds and pictures. When I go back and check the pictures to see if any of them are Pro, they all say they're free photos. Any help or advice would be appreciated. Thanks.
