In a modal, there are 3 columns.
All the DIV inside where created with Copy Block (linked) of the very first element.
I tried to remove the Virtual Class of element but it is same issue.

Hi @weedor,
Sorry about the trouble you’re experiencing.
The globe icon you see in the editor is a placeholder, meaning that on the frontend if no specific icon has been selected, no icon will appear.
Be sure to actually set an icon.
Please let me know if this helps.
I feel stupid.
All is ok, I thought globe icon was a “real” icon, so I didn’t go further.
Thank you very much.
No problem 
This might be a point to bring up with @Louis, to make placeholder icons “real” on the frontend.
I will post a feature request.
Thank you @Araminta
