This definitely warrants discussion with your supervisor. It's your supervisor's responsibility to explain what your role is on the "team" and how you're expected to fill it.(Obviously, this applies to all team members.) It's your responsibility to make sure you understand what the expectations are. If you're not sure, ask! Often, these situations involve poor communication of contributions/expectations rather than lack of skills. Keep in mind that just because someone has the role of supervisor doesn't mean they have all the skills required for that role.

After the discussion you may realize that you are not a team player, at least in the sense that your organization wants, and that's okay. You may just be in the wrong place.
