I wanted emulate this double header: LINK I’m totally destroyed, I can’t! the first header it’s ok, but I can’t do the second.
This is my canvas:
On the picture:
1- My canvas arrangement
2- Red block goes over the top.

3- I tryed to change the order in the lower layer to avoid it, there it gets out of control, even moving the light blue box that I have ordered to be fixed.
I can’t stick the light blue block named: Buy block, and that all the rest of pages (red) passing below (not above).
*If the order of creation of this light blue block, (it’s the last one), is the main problem, it’s crazy, because I can’t go back in time, and I could only start everything from 0, but I’ve already tried to do it on a blank page with no results, it’s as if I memorize the order of creation of its origin when pasting.
Please help, I will appreciate it!
