Hi, after installing Odoo 11, activating Website Builder and selecting a first template for our site (Clean), we want to switch and try out other (prepacked) templates from Odoo. But when going to edit mode and change theme settings, we are only able to do some basic color and font settings of the one installed Clean template. According to https://www.youtube.com/watch?v=tlLVQtrt66c

we should be able to select between several themes through a selector window. What am I missing? thanks in advance
