Widget Edit

Hey,
Im currently using the Mystique theme.

I have a widget that allows me to place adsense in the lift “secondary sidebar” and If I label it adsense there is a little arrow that says adsense and points to it and if I don’t label it, it still has an arrow with no text. is there a way to code out the arrow part? I would like to do it only for the adsense and keep the rest of the label for the rest of widgets I have if possible.

Thanks,
-Brandon
