Rich text styled icon failure

I am trialing the software and I am having trouble with styled icons in the rich text field.  The two issues are:

1. The information in the tutorial does not match the Appian software.  If I chose "styled icon"  for the rich text field, there is no "icon" item in the configuration menu as shown in the tutorial. It might be useful if someone updated this, at least it would be less confusing.

2.  The more challenging problem is that if I do attempt to create the styled icon, it only shows the text and not the icon.

I enter this in the editor:

if(

ri!vehicle.availability,

"check",

"remove"

)

According to the tutorial this should show either a checkmark or an "x".  However all this does is show the words: "check" or "remove".

Any suggestions?

Thanks!
