accumulating cancel/save buttons with repeated clicks, color not found

(1) when the annotation is clicked upon multiple times (without refreshing page), the cancel/save buttons multiply with each click (concatenated vertically) (2) when the colors for tags are more complex colors (e.g. "orangered", "lawngreen") they don't render correctly, but simpler colors work ok.

It seems that multiple cancel\save buttons is a problem of a greater scale. Any solutions?
