If you want to display a single category FAQ items in page then you defiantly don't want to show the title of that category before the FAQ items. Because you're page already displaying that category name in title. So, it could be odd sometimes(reported by some of our customer).
To hide the title you just need to add following code and make sure 'list' value is set to 0.[bwla_faq faq_category="introduction" sbox="0" list="0" /]
