Shopify Search & Discovery

Under “Search & Discovery” app’s Recommendations tab, I have put 3 specific items in the Related Products column for each of my products (a total of 8 products), yet on the live website, the You May also like section only displays, 1 or 2 items, not all 3 items I’ve specified, and it is inconsistent in it's display tendencies. The settings within Shopify (Maximum products to show) for the “Related Products” is set to 3. Why am I seeing less than 3 items displayed on the live site?

This app sort of does what I want, but not exactly as I want, therefore, 3 stars. Please work to improve this.
