Not compatible with Divi Builder?

Hello!

I cannot get the plugin to work… whenever I change the availability to “logged in users” after it’s saved, the setting is changed to “everyone” again.
I’m building pages with Divi Builder and it works with the pages itself, but it doesn’t work with the media ( mainly with docs and pdfs as they are not downloaded, just shown in another tab).
The pdf/doc file is visible for everyone with the file url ??
