When I go to settings from an internet page and Privacy -Delete personal data the image above comes up with no check marks.
You can tick one of the items and the "done" label highlights..
This image came from my wife's identical Galaxy4 10.1 tablet. As you can see three of the boxes are checked by default. You have to tick
a 4th one for the "done" label to highlight. It can be any combination of four.
I have looked at all settings and can see no difference in our settings.
