Disable Lock Screen on MacBook Pro

I'm trying to synchronise my OneDrive with a large number of videos / photos, but my MacBook screen keeps locking and asking me for password when I re-access, then I'm having to re-start my OneDrive sync.

I've tried to change the settings so that the screensaver and lock screen Never come on (MacBook is plugged into power), but it is ignoring my settings and locking my MacBook down.

Is there a way of disabling the lock screen, so that I can allow my OneDrive to synchronise without me having to twiddle the touchpad in order for the MacBook to stay active?

I have previously posted this, but for some reason it's not showing up in my subscriptions, but remember someone commenting that I need to update my device, this has now been done, but didn't change anything.
