I tried to do it on your advice. After the suggested settings, I get the following:
1) Click Edit>Update Your Profile
2) Check the Checkbox
3) Click Update
4) Click Edit>Update Your Profile again
5) I see that the checkbox is hidden
6) Click Update
7) I See that the Checkbox has Appeared and the mark is removed.
The hidden checkbox is unchecked without authorization after updating the profile
PS: If this is important: Edit Style - Buttons
