rounding 1st after a walk

[Stan]

8th grade girls, FED rules. After a base on balls, the runner rounds first and continues on to second with out stopping, runner that was on third with a lead off the bag, ready to go if they throw to second. Catcher throws ball to pitcher in the circle who doesn't make or attempt a play. Umpire made the girl go back to first because she wasn't 1/3 of the way to second before the pitcher recieved the ball. Where did this come from? Umpire was young so I didn't think It was an old unlearned rule. Are FED and ASA the same on this?

Thanks, Stan
