[SOLVED] dotted line when using page-center tag

I can't seem to get rid of the dotted lines at either side of the page menu when I use the page-center tag. If I use the pages tag, the dotted lines disappear, but I don't think I'm forgetting to style them anywhere. They seem to be built in to page-center. See here

thanks for any help.
