There seems to be a bug with the Navigator when changing the selected date forward. For example, if the navigator is currently on September 26th and the number of months to display is 1 and I assign the new date to show as October 3rd. It will try to display this within the September month and never display October at all(see picture1).
Now if I was to move forward another week, and select October 10th, it would show the month of October the way it's supposed to. And if I was to go backwards and select October 3rd again, it would display just fine(see picture2). It only seems to be an issue when moving forward from one month to another.
