bullet list formatting lost inside accordion

Have built an accordion, and used the integrated WP editor to identify a bulleted list inside one of the accordion detail sections. Looking at the text tab verifies that the UL and LI tags are all present as they should be. But when I insert the shortcode into a page and look at the page, the list is completely unformatted, as if it were ignoring the UL and LI tags completely.
