Change the number of products in a row in the recommended products section

Trying to change the number of products displayed in one row on the product card in the recommended products section.

I have modified the code and changed the max quantity, but there is a problem like in the attached screenshot, i.e. 4 products are displayed and 1 field is empty. Why does this happen and how can I fix it?

"type": "range",
      "id": "columns_desktop",
      "min": 1,
      "max": 5,
      "step": 1,
      "default": 4,
      "label": "t:sections.product-recommendations.settings.columns_desktop.label"
    },

As I have checked the store ,there is code with limit 4 for products,

or you have set in the product recommend customizer setting to 5?

Only on this type of product I have 5 products in a row, until it works fully, I do not want to run it everywhere.
