Hiya,
What everybody has said is totally right.
It's normal for GSD pups ears to be a bit odd at that age. I think it is mainly to do with teething (although it may not always be the case)
It's not something to worry about, as most GSD pups ears will go up in time. I've heard of it taking upto 6 months, but the latest, with mine has been 14 or 15 weeks.
I really think, in a couple of weeks your pups ears will both be up....I know I worried with my first GSD that one ear was flopping over...it soon came up and then I worried that his ears were too big for his head!!!
Take care, and good luck with your pup.
