Gaps on Product Page

Hi, I am using Emporium – WooCommerce WordPress Theme and am getting blank spaces on my product page the same size a product would be when I sort by default or alphabetically.

All the products are there, however it shows 3 products on the first line, 3 on the second line, 1 on the third, 3 on the 4th and two on the 5th. However, when I sort by Price it corrects the issue (i.e 3 products shown on every line).

Have giving the products ‘order’ numbers however that just made it worse.

Very new to all this, site is in construction still so don’t think I can post the link.

Any help would be greatly appreciated.
