Custom shapes in Photoshop

Hi,

I have the up to date version of Photoshop but I can't find the custom shapes I need. When I go to Custom Shapes all I see are:  Leaf Trees, Wild Animals. Boats and Flowers. 

What am I doing wrong?  Where are the other shapes? At the moment I'm looking for speech bubbles, but I know I'll need other shapes going forward.
