Cannot add multiple Yoast FAQs blocks to page

Hello. I want to add the Yoast FAQ block to a page. I’ve added the first Yoast FAQ block. I then added a heading and want to add more FAQ blocks. But when I try add additional ones the FAQ block is greyed out.

I saw on another closed topic on here that this used to be the case, you could only have one block but that this was updated and you could now add multiple. Using the latest version of Yoast. Latest wordpress.

I want to have FAQs grouped together under different headings.
