Because this gets posted every single day. You’re paired in to lobbies based on what you ready up with, not your settings.

You’re still playing in Xbox lobbies even if the setting is turned on 

Yeah it is. I wonder what is going on with it. 

The cross platform parties toggle bottle is bugged on Xbox and users cannot switch the setting to off. The cross platform parties toggle button is stuck to “on” regardless of switching and confirming. I believe this came with the most recent system update. Beware, once it is switched switched on, it cannot be switched back. Epic please fix this.
