WP [caption] image insert adds a 'dash' to the caption text

I have images with captions inserted using [caption] tag (top right, Home page and Reviews page). In both cases there is a '-' added before the caption text begins, and the caption text is padded on the left to make room for it. If I reduce/remove the left padding the text overlaps the '-' .
The caption text is in a <p class="wp-caption-text"> with position: relative;
If I remove the position from the class, the '-' moves to a spot just above and to the left of the .entry_content h1 at the top of the page. An suggestions for removing it?
