Im trying to set up a similar product and have set a field for it. / Ive even tried to alter whats there to no avail.

When I go to
DESCRIPTION
It only allows me to type in 22 font (plus bold / italic /underline)
I cannot set the font to a different style ?
secondly
When I try to put in a label from my Image store a single click highlights the chosen label and a double click unhighlights it ?
Ive spent ages on Youtube and cannot solve it
