2 items across instead of 3? Does it update from etsy?

Hi, after a few problems I’ve finally got it to work ok, thank you.

Only problem for me is it shows 3 items across whereas my centre area is only two items across . I have partially solved the problem by knocking out the right hand sidebar on this page, but they still extend over the edges of the central display area. It would be nice to have an option as to the size of the table. Other than that they do look nice

Secondly, how/when does it update from Etsy, if ever? I mean if I add a new item to etsy (which I just have) it hasn’t updated on the website in real time, so I am wondering if it does that at all or if there is something else I have to do to make the new items show up?
