Can’t Add New Shortcodes of my Own

I can use the existing tutorial shortcuts but as they can only be used visually unlike other similar products, can’t use any shortcuts that I have created. The probable reason is the icon editor/selector is broken and it wants an icon to display (or else, I’d call that a bug, should default)

This looks like a very powerful product let down by zero documentation, not even the basic basics.

I’m giving it one star as support emails are unanswered.
