Did you get anywhere with this issue? I'm working on facets for filtering on an ecommerce site and the ability to show details of the principle filter is essential.
Many thanks @TR. I applied the patch to fix the issue, but it turns out it was caused by a faulty mimemail template in the theme folder. Long story short, I am switching back to php 7.4 as there seems to be fewer issues with the several custom modules I inherited.
I appreciate the suggested fix though - thank you.

Thanks for a reply @TR! Revealed code from the first part of the email attached (I assume this is what you're after?).

@perfectcu.be wonderful support, thank you. I no longer need this module as my customer looked for a different solution (I had this issue 2 years ago). Now working mainly with BackdropCMS, so might revisit this, with your help.
