Autcomplete results not showing distinct items

Hi,

I am setting up Algolia on my Shopify site (running debut theme) and the results showing up in the Autocomplete bar are showing all variants for each product, but I only want distinct products to show. I have my distinct value and attributeForDistinct value set in settings.

My instant search page does not have this problem, and is showing distinct products as expected.

Is there a reason why this is different for the autocomplete hits and not the instant search page hits? And anyone know how I might fix it? The way I am going about my Algolia setup is by extending the widget.

Thanks.
