Short Product Description (WooCommerce)

I am trying to optimize a product page and in the short description i enter in information and Yoast SEO is happy and gives green light, but when i save, it says its too short.

I then add just enough text so that the green light goes on and then save again and then Yoast still says its too short after saying it was a good length.

If i add more text, it then satisfies it and then on save it now says too long.

frustrating as i want the green light on this page, but the short description is not allowing this to happen.
