Why is 'cars %>% filter (cylinders == 8, mpg > 18)' returning an incorrect value in R?

My code is: cars %>% filter (cylinders == 8, mpg > 18) and is returning the results shown in the photo attached - https://i.stack.imgur.com/n86ZY.png.

The results are all correct aside from the top row which has a mpg of 9. Why is this result being included and how do I rectify this?
