Dynamic block backlinks to this-heading-only doesn't work?

[novakwh]

Hello, when I include :this-heading-only t into the denote-org-extras-dblock-insert-backlinks section, it continues to list all backlinks, not only those notes with a link to the heading in which the block is located. Am I doing something wrong?

#+BEGIN: denote-backlinks :sort-by-component nil :reverse-sort nil :id-only nil :this-heading-only t

#+END:

I have confirmed that one note is linked correctly to the org-heading (using denote-org-extras-backlinks-for-heading) and none of the other notes are linked to anything but the note itself. But they all show up inside this block.

Thanks for your help!
