Adrienne Lovette's credit is locked as being verified as corrected by IMDb. However, it is unordered and she should have the attribute as "uncredited" and her character should be "Cora's Cellmate". (She is credited this way in Episode 2)
The episode credits for Adrienne Lovette are listed correctly with the character name "Cora's Cellmate", we have also now adjusted the applicable episode credit with the "uncredited" attribute, this change should be live on the site shortly. Cheers!
