Printing problem

I have a problem with printing.
I am trying to print from two layouts. With the first the preview shows me exactly what I want to print (07/03/21a).
The second layout 07/03/21b is totally blank so I cannot print. Why is that?
It is actually a copy of the first and I cannot see any faults with the settings.

OK I can see I made a mistake.
In 07/03/21b printing background is white when it should be grey.

Coordinate marker or ucs is not visible on lower left. I try clicking everywhere but it does not appear. What am I doing wrong?
