I have same issue, as also seen in another discussion: https://github.com/orgs/community/discussions/64473 . This might be related to cache key reserves, but there is no way to delete them.

gh CLI:

gh api -H "Accept: application/vnd.github+json"  -H "X-GitHub-Api-Version: 2022-11-28"  "/repos/{owner}/{repo}/actions/caches"
