I posted my reply late at night, so I forgot to add the most important thing - with that much white on her, I very much doubt your girl is purebred. But if you have no plans to breed her, that's not a problem. She can still be a wonderful dog.
As for her acting like a GSD, I have 2 GSDs, one is a show line, the other a working line. They are very different in their temperaments. The show line is calmer, and less distractable, but has a stubborn streak that makes training a challenge sometimes. The working line is young, very energetic, and tends to get distracted by people/other dogs/ cars, etc. so teaching her to focus on me can be a challenge.
As Dotbat said, you need to train the dog in front of you, and not make assumptions about how she's going to act a certain way due to her breeding.
