If the values you are entering into the settings are not valid you can get an error message about them. Please post back with a specific example of one of the settings that you are trying to update and the results that you are getting. Please also include the exact values that you are using, any screenshots of the error would be very helpful as well.
If this is a more involved problem or an issue that we would need to get some more detailed info about I can open a ticket for you so we can exchange the details in private.
