My Doberman had her ears done and I ended up with a Dobe with one up and one 'sideways' like your dogs. I disliked the look for a while and then made the decision to like her quirky look. One day when she was over two years old I was out taking pictures and suddenly stopped. Both ears were up. I don't know when that ear finally went up, but it was after she was eighteen months old as I went back and checked some old pictures. It never went back down. It just took years to go all the way up. Don't give up hope it will eventually stand.
