How to make shelves appear in the new Goodreads recommendations section

Hello! I have a question about the new recommendation set up on Goodreads. I updated my Goodreads last night, and from the few minutes experience that I’ve had with it so far this morning, I really love it so far! Question is about the new recommendations tab. I have my shelves set to give recommendations along with my genres. But when I go to the recommendations tab in Goodreads app, I don’t see my shelf recommendations. I only see my genre recommendations. But when I go To the website, I see my shop and genre recommendations. My question is, how do I get my shelves to show up along with my genres in the new recommendations tab on Goodreads? Thank you in advance!
