Hi,
Think this is a bug in the campaign editor. Every time we try to set image area padding to zero, the UI sets it back to 9px and 18px when we tab out and back in again, or when we exit the content editor and go back in again. I recorded some screen video which shows the issue.
If this is being reset due to a conflict with other settings in the UI, then a message saying why padding is being reset is needed.
Many thanks,
G
