To reproduce the error: 1) Use Firefox 2) Upload any new cohort 3) Add a tag to the cohort 4) Click on the cohorts tab (left menu) various times It seems there's some lost event listener that catches every click after adding a tag and adds another tag. Also it eclipses the refresh button functionality, I think.
