Each class section begins with {| and it's closed with |}. For the mw-collapsible class to apply to the entire template and be inside the first header, the five class sections must not have |} closing each section. Instead, they should just be separated by |- and then the start of the next class {|. Only close the last section with |}. You also had some extra pipe bars you didn't need.

You see what I mean here?
