GitHub releases not available in record

I've just saved swh:1:snp:952376399ae6bf9fdbc352f754685e6b947a81fe;origin=https://github.com/citation-file-format/cff-converter-python, and have discovered that it gives the number of releases as 0, as compared to the 17 releases in the repo: https://github.com/citation-file-format/cff-converter-python/releases.

I would expect the relesae tab in the Archive page for this repository to list the 17 releases. The release tags are still available via the branch drowpdown (e.g., refs/tags/1.3.3 for the last release).
