Membership Pro 2 Protecting PDFs isn't Working for Me

I've tried protecting a PDF in membership pro 2 so only members can see it. I've tried using the media add on to do this, and I've also tried protecting the specific URL but still it isn't working. I'm sure it's something obvious I've missed.

I've granted support access should you need it.

So these are the files and it's showing them to everyone instead of just members. I've tried the uploads file as well as the downloads file.
