Howdy,

We’ve just upgraded to 3.1.4 and noticed two issues.
#1 there is a rogue > on the left hand side of the menu
#2 The CSS for making a menu link item to a button doesn’t work for either of the button options (now disabled)
The first one is annoying, #2 we can live with :) And the link is the private content section below.
