Default Loosen option : home button for default page

I'm about to be crazy, because I've loosen an option.
I just want a simple thing : that the home button goes to the default page on nova (null 23).
I've selected the nova option / button / default page (and the option 'only screen... ' ticked and not ticked) .
but when the watch is off, I press home button once and it goes to the last screen, another press and it goes to default page.

I remember an option where It was possible to select 'last page' or 'clock' but I can't find it anymore...

Could you help me?
