My guess is that it ships with extra wire that is intended to be cut. Better to have too much than not enough. Cut it as short as possible and you should be fine. Quite often in many systems, from small electronics to huge high voltage system the ground is an exposed wire or bus. It's not a problem if you install it correctly (meaning trim the wire) and make sure it doesn't touch anything else.
Short version: exposed, and even braided, grounds are common.
