Button "Download a copy" ONLY works on the "All Items" view of document library

This is a problem that I have with every document library in our environment.



I have enabled the option to download a copy, for every library. When I look at the "All Items" view of a document library, I can download a copy of an individual document just fine (I highlight a document, then the tabs "FILES" and "LIBRARY" appear at the top, then I select the "FILES" tab, then I click the "Download a Copy" button).

However, if I use a different view from the same library, suddenly the "Download a Copy" button (and many other buttons) are no longer enabled.

Upon hovering over it, it says something in the lines of "This element is currently disabled", even though it worked just fine in the "All Items" view and even though I set the library to allow documents to be downloaded.



I've been searching through settings of multiple libraries and can't see why it doesn't allow some buttons to work when I'm using a view I've made myself. Even when I make an exact copy of the "All Items" view, then that view still won't even have those buttons enabled.

I have full control on all libraries, so I'm not suspecting it has to do with permissions.



Since I have absolutely no idea what might cause this, any help would be greatly appreciated!



EDIT:

Just to make it clear, I'm trying to find out how to download a -single- document from a library. Not how to download all documents at once. I just need the "Download a Copy" to be enabled in all my views, and would like to find out how to do so.



EDIT 2:

Not sure if this is relevant, but all my browsers (FireFox, Chrome, IE) are 32-bit versions.
