If you delete all the boxes from a block there is an option to add a box. However, the add a box link generates an error:
Argument 1 passed to backdrop_sort() must be of the type array, string given, called in /app/src/modules/contrib/fanciblock/fanciblock.box.admin.inc on line 9
NOTE: There is no option to add a box to a block that already has at least one box. It would be nice to be able to add and delete boxes.
