Homepage Review display bug

Hi, something strange is happening with the reviews on my website, I created a tour and I added my first review on it to test it. The review added was 5 stars and it shows correct in the tour inner page, however on the homepage under the top reviews section, the same review is showing as 2 stars! check the screen shots below:

And to confirm, this is the only review added in the system. Please advise, thank you.
