I just find it impossible to see what different settings does in the small preview window.
The black paper arrived and the first test is quite promising. Here is the page 8 scan again without black paper on the left and with on the right.

Now, I was a bit surprised because I thought the unwanted see-through print would come from page seven (the back of the sheet that page eight is printed on) but then my eyes fell on the area left and below the byline. I could actually make out a few words which was strange as they should be backwards (or mirror-turned as we say in Swedish).
Looking at page six I did indeed see those words. So the strongest see-through print actually comes from not the same sheet but the one under. I'm sure this was obvious to you but to me it wasn't.
