Desktops MacBook Air

I have a Macbook Air with Sequoia 15.0.1 operating system and for about two months, the zoom screen image replicates on all 9 desktops of the Mac! Does anyone know how to see it only on one of the desktops and leave the others free?  I want to let you know that I have the same problem with QuickTime Player whose image I see replicated on all 9 desktops of my Mac!

Thanks for your attention.
