Since it's only been 10 days a couple things could have happened. I think the most likely is that it's a trail that possibly isn't a "real" high traffic area and by you moving back onto the trail you pushed em' off. I'd leave the camera alone for a couple weeks and they should go back to using it. Thing #2 is if it is a real high traffic area and your deer seem to have dissipated, stay out of it and don't pressure the deer. Hope this helps.
