After discussing with the team, most likely this is a result of another issue: https://github.com/ethersphere/bee/issues/3037

The team is working on a fix, however this requires architectural changes to the localstore component and that means basically of a rewrite of the undelying data storage. The estimation currently is that it will be released somewhere in autumn. You can keep track of all related issues in this issue: https://github.com/ethersphere/bee-backlog/issues/41

I have seen this unpinning issue when one of the component chunks under the reference, or the reference itself, is unavailable locally and the traversal fails. This can happen when chunks are randomly, and incorrectly, unpinned by an over-zealous reserve purge. See also #3037

Same for this one I guess. This whole mechanism has changed so better to file new issues for pinning/reserve interactions.
