Not sure I understand what you mean. It is inside the columns, i believe.
I have used short-codes for my font-awesome icons now, and it works fine.
Since it is only me that is going to work with the site, its OK. But a problem may arise if someone else starts to put tekst into the sections.
GeneratePress is a great framework, by the way. Very pleased with the ease one can modify the content and the looks of the site.
