check your box and see if it says 2.0 on the sticker area. you may have just gotten an early run trigger frame with only one LED. my 2.0 came in a 2.0 box with all the 2.0 ups[valve, bolt, board, arms, etc.] BUT, only had one led and diff frame. should operate the same as any 2.0.
otherwise, contact the place where you bought it.
