Reporting leadership positions on Common App confusion

I want to make sure I’m reporting my leadership honestly. So here’s my confusion, represented by a hypothetical scenario. Say I was on the volleyball team for years 9,10,11, and 12 and served as team captain during years 11 and 12. I would put “volleyball team” in name of EC, then put captain as my under Position/ Leadership description, correct? Then, I would mark that I participated in this EC in years 9,10,11 and 12. Wouldn’t that imply that I served as captain for all four years, even though I only did it for two years? There’s nowhere to mark the years that you held that leadership position. I just don’t want to be misleading at all.

Next to captain I would put “(11-12)”. At least that’s how I filled out the leadership positions.

I put “Team Captain; Varsity Cross Country” on the heading part. I had many other things to fill in the details box. I served as a captain on the team for all three years but I feel like the years are irrelevant.
