I believe that when you look at older Hilton emails the points that show there is the current balance. I don't know why they do this as it just creates situations like you have now. I just had some points post today and I looked at emails from 9/4 and 9/12 and both show my current and accurate balance. I have tracked my points using an Excel spreadsheet since 4/2016 and it is time well spent just so I don't think I'm missing any points. I've yet to have something not post (+ or -) incorrectly. YMMV.
