Affiliate Plugin Shortcodes / Layout

I’ve installed the Affliate program plugin, but for some reason the layout is showing funny. If you look at the attached file, you can see what the tutorial shows – the layout as it should be – and then as it currently is (squashed/out of line and without borders around the boxes).

I’ve used the shortcodes as per the instructions on the tutorial, but I can’t find how or where to fix it so it looks professional as it does is the tutorial.

Any help would be appreciated :slight_smile:
