As long as you have her on Stafford passport I don't think you can hope for better. She MAY be a mix, but she certainly does look Staffy.
I would not suggest she may be mixed with bull mastiff as those dogs are on Germany's dangerous dog list while Staffy's are not (?).
Regardless, it really doesn't matter what we think ... the dog wardens will form their own opinions as they feel required. So keep the paper work straight and ensure there is no paper trail with an affiliation to "aggressive and dangerous" breeds.
