Two buttons Request a Quote

Good evening, I am working on a development site with WordPress, DIVI version 4, Woocommerce, and the Yith Request a Quote plugin.

I used the shortcode [yith_ywraq_button_quote] to insert the button into the product page, but I noticed that the same button still appears at the top left of the page.

You can see the effect in this image: https://drive.google.com/file/d/1ezkkLu8M11mnXuJuoUHd2t2c7QPM8uD0/view?usp=sharing

There are therefore two buttons on the same page.
What did I do wrong?
Thank you, Roberto
