After reviewing the photos, it looks like one half of the caliper, that being the half that mounts to the fork, is 2 pieces of press fit metal. That press fit has come loose and is causing the caliper to slide along it left-to-right, making it operate kinda like most automotive calipers.
:EDIT: It might be designed to operate like this, there could be a spring behind that plate being held by 3 screws.
