Name Conflation Cleanup: Duplicate cast credit blocking correction on "A Sweet and Vicious Beauty" (2012)

I am trying to clean up a persistent name conflation error on the indie movie A Sweet and Vicious Beauty (2012) [tt2438658], but the automated form is rejecting the edit with a duplicate character warning.

Currently, the role of "Farmhouse Wife" is listed twice under the cast page:

1. It is mistakenly attached to the high-profile Hollywood producer Caroline Alderson [nm5311198] (who is listed in the top cast).
2. It is correctly attached to the actual actress who lives in Takoma Park MD near where the movie was shot, Caroline Alderson (II) [nm11827520] (listed further down the full cast).

The producer Caroline Alderson never appeared in this indie film; she was starting her career in Los Angeles/UK production at the time. The credit completely belongs to the actress profile [nm11827520].

Because the actress profile is already listed in the cast, the automated edit form rejects my correction to change the producer's credit to Alderson, Caroline (II), stating "This person is already part of the current contribution."

Could a data editor please manually remove the "Farmhouse Wife" credit from producer Caroline Alderson [nm5311198] and ensure it is fully consolidated under actress Caroline Alderson (II) [nm11827520]?

Thank you for your help.
