In the installation only some of the default params for com_content are setup in the database. It's not really a problem as there are default values BUT it means that where you have a setting in a menu item that is "Use Global" it doesn't display the value.
Hint for other testers: Just make a new installation with the patch of this PR applied. Then verify that the params of the com_content extension in database are the same as before when you have opened and then saved the com_content parameters in backend.
