Having issues filling out the activities section of the common app

In 11th grade, I was the Vice President of my old school’s NHS fraction. However, in my 12-grade year, I, unfortunately, had to change schools. So how do I describe this on my application?
Do I put NHS VP? Or NHS Member ??

This person also changed schools between his junior and senior year. Minute 4:40 is where he shows what he put down for NHS.

Thank you! One more question, I ran for student government twice and got two different positions (treasurer and secretary) Is that all included as one activity? Or do I lest them separately?
