Layout they don't change

Hi,
I have two layouts. I send the first one to the display. If I want to change it and add the second one, the first one will always stay. If I modify the first one, the changes will be visible.
What could it be?

Thanks
Francesco

We are missing some data here. Layouts are only for the view like a powerpoint slide. If you want to display both, then they will need to be both added to a schedule. The schedule needs to be allowed to run indefinitely.

Hopefully that helps.
