I use the tag $#ZISROUND#==true?100:0$ to show a green circle with seconds, if you select a square watch face, the circle is not shown. In Facer Creator edit mode, this works fine, but when you look at the preview in the publish/update window, it either doesn’t display at all or is displayed on both dials.
