Check vs Grey square

Just wanted to ask if someone could briefly explain what the differences for the following settings are in leaving them on the grey box, vs a checkmark.

I’m not entirely sure what the difference is. Should I leave it on one or the other? Are there situations where one of these settings should be set to specifically a checkmark or specifically a grey box?

Hi Cam,

On mobile so so can’t quite find it, but, that same question was asked and answered in the past month or so by jussi so in this section. Try a search in this section sorted by recent date.

If you hover mouse cursor over the box you get tooltip hint appearing describing what the settings do.
