The three marked boxes are only options to identify them for further editing if you wish.
You can mark all of them Mark one if you like then go back and use the box. line and border to change the colours, fill and shadow etc to anything you like
Think of the three mark options as an ID tool so you can see them in the chart then edit them as you wish
In other words you can change the ID marks to anything you wish
To coin a phrase, "you have to think outside the boxes" :-)
