There’s no way to purge them at the moment, you’d have to delete them manually from the sync target (eg. delete resources/0f23dd26afef41cc89936a928024839f and 0f23dd26afef41cc89936a928024839f.md).
It wouldn’t be the cause of tags no syncing since if these resources show up in the status screen it means they’ve been dealt with and are skipped during sync, so the two problems are probably unrelated.
