gush issue:list --filter=assigned is listing all open issues

I've installed gush using composer global require gushphp/gush=dev-master all is working fine, but gush issue:list --filter=assigned is listing all open issues, it seems as filters are not recognized. The same happens with --filter=created

Repo I'm using is https://github.com/quailjs/quail/issues/assigned/attiks?state=open
