weekday/ weeknight breakdown

Now I am having strange thing with weekend/weekday night rate.
My weekend nights are defined as Thu, Fri, Sat, Sun. My weekdays Nights are defined as Mon, Tue, Wed.
Here is a quote from the rate tester 3/1 thru 3/7 2017.
Rent 1 night (3/1) during Low season Winter 2017 at Weekday Night rate $145.00
Rent 5 nights (3/2 - 3/6) during Low season Winter 2017 at Weekend Night rate at $169.00 per Weekend Night $845.00
I am not sure how is it counting 5 weekend nights if I have only 4 weekend nights defined in a week? The nights of 3/1 and 3/6 should be weekday nights, not weekend nights?
What am I doing wrong? thanks

@u0999: I don't think you're wrong. I think you found a bug. I can definitely reproduce it on my end and have no immediate answer. I'll have to get back into the lab and huddle on this.

Thanks, I think I am on the roll finding things :-) I am setting and testing rates for 2017, so that is how I found this.

FIXED! We were able to locate it fast, patch it and push a release for it. Try it now and that shouldn't happen again. Great find.
