Hello,
Thank you for contacting Rank Math and bringing your concern to our attention. I’m sorry for the delay and for any inconvenience this issue may have caused you.
Please note that you can only set a post, page, or custom post type as pillar content.
You cannot set taxonomy terms as pillar content, as they are mostly archive pages and provide little to no value to the reader.
Here’s a link for more information about pillar content:

Looking forward to helping you.
Thank you.
