Stars Displaying Incorrect Rating (4.8 Showing as 5)

Hello! When manually setting the rating in the badge to 4.8, the stars are displayed correctly in the preview, with the last star partially filled. However, on the site (I insert the shortcode in Gutenberg), all the stars are fully filled, as if the rating is exactly 5 and not 4.8. How can this issue be resolved?
