Different URL but same products

Hi SEO pros

Suppose if a site (built on Shopify) has two URLs domain (.)com/collections/sleep-solutions/brand-XYZ and domain (.) com/collections/featured-collection/brand-XYZ (both of these URLs are category pages and show the same collection of products) and both of these are getting indexed on Google. WHat title and h1 would you give to these pages, and should I deindex any of these pages?
