ok your problem here is, you are trying to edit the wrong thing! Those are the constraints on the actual columns. You need to click on the 'data' tab up above , where you can then change all the startup location data ( this is also true for any table in the database)
so, set all of those back to 11 ( their default value), then click on the 'data' tab above that, and it will alllllll make sense
