@Rosemary11 The 9th stay still counts toward your total number of stays, regardless of whether they leave a review. But it usually takes a day or two after the checkout date before your Progress bar is updated. Also bear in mind, the IT can be very glitchy - some days it might display something like "1100% Acceptance Rate" or "0.9 Star Average," so it isn't worth taking seriously.
Hosts have no control over the way their reviews are presented, and it actually varies quite a lot depending on which country or language you're viewing the listing from. Asking for changes in this regard is a lost cause, but you don't have many reviews yet so there's no danger of your best ones being hard to find.
