As a bicycle store owner for over 12 years, womens cycling coach and a guy who developed the pinpoint size system and raced three years as a junior as well as 1-2 pro for five years, I can tell you without a doubt that your seat is way too high. The simple fact is that you clearly have your leg so extended that you have absolutely no ability to drop your heel(s) to help turn big gears up while climbing/ going up hills.
