Script consultant

Hi. I’m finding contradictory information about which section a “Script consultant” credit should be in. I have been given this credit on a film on which I did two uncredited script passes, including writing entire scenes and quite a lot of dialogue. I had absolutely nothing to do with on set continuity, and don’t think the credit really belongs in the script and continuity section. I agreed to work without a writing credit as the producer had original employed an elder statesman screenwriter at the end of his career and didn’t want to embarrass him by diluting his credit, so I can’t easily go to the writing section. I’m happy in Additional Crew. Isn’t that where I should be?
