Hide Shipping Calculator

Hello,
I added a plugin recently to my page for shipping costs. Before this, I used the integrated Woocommerce calculator. Now, that I have the plugin, I want to get rid of it, but it seems not to be possible. I already disabled it in the Woocommerce – Settings – Shiiping, but it is still showing in the single product pages.

Anyone has an idea how to remove it?

Regards.
