3 products on main page with left menu

[gbartosz83]

Hello, I have a little problem with displaying products on main page.
I wanted to have menu with all categories and products on main page, so I have changed grid for index to "Two columns small left column - Two columns with a small left column".
But now in the main page only two products in one row are displayed (instead of 3) 
How to change this to look the same as in category view where 3 products are displayed in a row.

this issue is in the popular products section, when I click "display all products" it display 3 products in a row.
