Assignee:none, other languages than english

Hi there,

I’m having issues on listing unassigned issues when using a selfhosted GitLab in other languages than English - tried German, Russian, French.
In the issues’ list I’m able to select “Assignee = None”.
But in non-English the URL is set to assignee_username instead of assignee_id.

I’ve not yet found this on the internet or as a GitLab issue.

Would be glad, if anybody had an idea.
