Statbox reload button doesn't clear previous team members

Every time the statbox refresh button is clicked, the team members are appended again.

If you choose to try fixing this issue, please also try giving the statbox refresh button a tooltip (title attribute?) saying what it does.

Start by locating the statbox refresh button and its click handler. Check how team members are rendered on repeated refreshes; done means refreshing no longer duplicates members and the button has a tooltip describing its action, then verify both behaviors with repeated clicks.
