What setting do you use in your environment, you have many different
settings
and I don't know which one of them do you use.
The one which is not commented.
I thought you want to arrange the pages with the "2SIDE" command but what
do you use is "2*2" and the in this case rightpage needs a frame on
the left side.
The setupbackgrounds command is now:
\setupbackgrounds[rightpage][leftframe=on]
