Issues with woocommerce and pricing tables

Hi,

Having a small issue with woocommerce and the theme’s pricing tables.

This middle plan/button does not add any plan to the shopping cart for some reason, whereas the other 2 plans work fine. Setup exactly the same and no changes made recently – all 3 plans used to work fine weeks ago. See here: https://metamode.com.au/plans-pricing/maintenance-plans/ http://prntscr.com/a9t1ym
