Default Items Per Row

On the main store page, I would like to show Categories in Grid Layout at 5 or more per row, but keep my products list at only 4 per row, but cannot determine how to do this. It appears as though the default items per row is set for both. I CAN do this on my Catalog pages by setting products at 4 per row there.

Hello Alan,

This is correct. That setting is used for both of categories list and products list. I will improve to make them as separately options soon.

Sincerely, Giang
