[Plugin: Wordbooker] meta description=… tag

Wordbooker emits a meta description tag (wordbooker.php lines 1729, 2473). There is no option to turn this off and if one uses any other plugin to manage meta tags (SEO, theme’s own settings etc) each page has duplicate meta tags. Is it possible that this plugin does not emit header tags that are not directly related to its function? Thanks
