How do I stop (incorrect) blocking due to explicit language?

I am trying to translate a document using SIRI ai and keep getting this message "That translation is blocked because explicit language is restricted in your settings". I am sure there is no explicit language in the document. I have tried to translate different documents with the same result. I have tried the Content&Privacy sliders in both directions. I am not aware of any restrictions on content on my Mac. Any suggestions on why I am getting this message?
