I just got a brand new hld-8 battery grip for my omd5ii. The landscape grip works fine. But when I attach the horizontal grip, I can't get all the knobs and dials to work. The shutter release on the battery grip and one of the dials do not work. And when I try to set the camera to choose the battery in the grip in the utility meny, it just goes back to the body option. It there something I have to do to activate the battery grip?
