I need an EXCEL EXPERT for a MAC

Job ID: 30919746

Budget: $30 – $250 USD

My new mac has 5 desktops, whenever I open an excel file it appears on ALL 5 DESKTOPS which makes scrolling between three different workbooks impossible. This is also happening with Chrome where I open my Gmail. I have tried researching for over 8 hours, no luck. WILL HIRE and pay well if someone can assist me to remove from the other 4 desktop screens.
