BUG: Banner is hidden when multiple banners are active

Hi, like your banner add-on.

Found a bug. The red banner is hidden behind the blue. It only is shown when the blue banner is closed. What I would have expected is that with multiple banners enabled they would be displayed under each other, stacked, not behind each other.

Additionally, the banner heights are very big for the single line of text being shown. how can I reduce the banner height to make them thinner?

Hope you can assist,
thanks
