Hey dude, I own the same exact product. Here is my experience with the screen protectors.
First off, there are two layers of protective plastic. There is one on each face of the protector. In between the two protective films is the actual screen protector. This threw me off at first because I was also getting tons of bubbles and smudges (since I was applying the wrong film). If you cannot distinguish which is the actual screen protector, look for the thickest piece.
As for the missing add-ins, contact Anker. They have great customer service.
Hope I helped!
