Change number of posts on category layout?

Hi there, at the moment if you view my category layout here you can see 6 posts in a 2 column layout: http://www.jamjosandbox.com/magazine/category/politics/ I would like to show 10 posts here. I have gone to settings > reading and changed the display to show 10 but nothing has changed on the frontend of the site. Is there some place else to change how many is displayed here? Thanks

Please check News2 -> Template Options -> Features tab and on the bottom you have settings connected with category grid, you've probably set 1 row x 2 columns in all 3 positions, but it's 6 total articles and you set 10 in settings -> reading. These values should be the same, so if you want to have 10 articles, please set i.e. 1th and 2th field to 2 rows x 2 columns and 3th to 1 rows x 1 column, then it should work properly (also with pagination)

Thank you very much, now I understand and that solved my issue.
