It's likely this issue predates Contrib.social: some issue and comment data are missing.
Closing this as outdated since it was reported against a now-unsupported version of the module and nobody else has reported the issue in recent versions. Feel free to reopen and update the version if you experience the issue in a currently-supported version of the module.
