Customize headers wrong date - bug?

The customized headers for month and day in the month view don’t reflect the actual date.

In the uploaded screen shots you can see I have the customized headers set to “Month” and " “Day of month”

At that point a 01 for the day appears next to August. But if you look at my gantt chart you can see that the task that starts Aug 2 is WAY before that.

I’m actually just trying to see the number of weeks in the month view but I can’t get that to work either.
