Thoughts Patrick?
The parking light filament, and the turn signal/brake filament, are indeed separate. However, they have a common ground. If the connection to the common connector is good, but from the common connector to the ground is faulty, it will back feed right up the other filament. Follow my previous instructions by running the two ten foot alligator clip lines and retest. If everything is exactly the same, then do the exact same thing with the two front bulbs using two more eight foot alligator clip lines, then retest (yes, you will have four temporary ground lines draped over the car).
