The problem is: there is no “save” button and all you can do is to exit the settings after the change.
Usually when you have a setting string and you put some info in it then you need to press “return” on your keyboard or something but there is no “return” key on a numeric keyboard also!!
So it’s kind a strange situation where you can’t set your changes.
