Apex Legends, switch screen when I click on "W", Shift and right click.

When I'm playing Apex Legends, when I click on W, Shift (Sprinting) and right click, the game switch monitors on me.  

I've already set the game for Fullscreen and I've tried the whole, Shift, the Windows logo and Right or Left arrow and it's still switches screen on me.

Is there a way that when you have the game set to one screen? I shouldn't have to turn off my other screen to have Apex Legends running on my main monitor. Any other games I don't have any issue except Apex.
