Your dock must be bent because the only reason it'd have a problem after applying it is because of that.
Also it covers the entire bezel and leaves the sensors and ports open... I mean I don't know what else you expected?
It doesn't cover the entire bezel, all sides are not fully covered. From what I seen all switch glass protectors don the same by leaving space on all sides. And I did the penny test on the dock, the penny slid up and down smoothly.
