Fix Broadcast Theme customisation

My Shopify store runs on the Broadcast theme and the collection-page sorter is giving me trouble. None of the customised sort options are showing in the drop-down, so shoppers can’t reorder products at all. Nothing else about the store is broken—just the visibility of those options.

Here’s what I need from you:

• Diagnose why the customised sort list isn’t being rendered (Liquid, JavaScript or theme-setting issue).
• Restore the full set of sort choices so they display and update the product grid correctly on every collection page.
• Keep all other theme styling and settings intact.

Please work directly in theme code (I’ll supply collaborator access) or through a duplicate theme if you prefer. Once complete I’ll verify on desktop and mobile that every sort option appears and reorders products instantly without a page refresh glitch.

Experience with Shopify Liquid, Broadcast theme structure, and AJAX sorting will help this go quickly. Let me know an estimated turnaround and any clarifications you need.
