Question on focus points in DPP

[mangurian]

• Sometimes when the focus point is very sharp and then I switch to show only points in focus there is no square. 
• Sometimes when the focus point is very sharp and then I switch to show only point in focus, the focus square is still black.

Looking for an explanation.  Thanks,
