Yes, in fact if I choose one or more pages (using the Ctrl), and then save the changes, the position of the content does not appear, respectively.
This is how it is supposed to function. The content doesn't appear on the pages you have selected in this area.
But this raises another question - as well as a selection of pages removed altogether, that is, if I want to cancel your previous choice should I choose an arbitrary page and save the changes?
I don't follow what you are asking here can you please rephrase or explain a bit more?
Thanks,
