Settings of Download / Media Options Not Masking Files Properly

I am trying to get a link to a PDF file I have uploaded to the WordPress media library to NOT show its true location on the server, when a subscriber hovers over it, clicks on it, or tries to copy it, within a post.

But, the options under “Download / Media Options” no matter what I set them to, are not properly masking the URL.

What am I doing wrong?

Will you kindly take a look at what I’ve got here, and let me know what can be done? When logged in a simple subscriber, with no admin function, I view this page and the actual link is not masked, but is rather exposed.

I’m trying to figure out how to get the masking to work.

If you need any other info from me, please do not hesitate to ask.

Thanks so much in advance for your input!
