Hello,
We checked your page and those parameters http://prntscr.com/vzqluh are related to texts you have in those sections, in your case – Product titles you have there and no matter in you use the 8theme Products element or default WooCommerce element like Product category https://gyazo.com/2d6a69165d8b6e1eb805947234af8f06 So, follow the link to find out how to improve that https://yoast.com/flesch-reading-ease-score/ and https://yoast.com/transition-words-why-and-how-to-use-them/ Also, you may contact SEO plugin support about this because the issue appears not just with our theme elements but with the default one that means that our theme is not the reason of the problem.
Regards
