Why cant i drag deselect in ortho or perspective?

Why cant i drag deselect in ortho or perspective?

According to Viewport Controls in Unreal Engine | Unreal Engine 5.9 Documentation | Epic Developer Community

I should be able to ctrl + right click and drag to deselct… it does nothing if im in the selection tool. It rotates the selection actors if im in any movement tool. I am trying this in ortho…

Shift + lmb + drag works for selecting more stuff…

wtf?

im in 5.8
