You're absolutely right, Microprosa. Short answer: The problem will be fixed shortly.
Long answer: When we moved to the new system of tools, the cast list is automatically generated from the episode transcripts; however, the system does not correctly resolve roles played by more than 1 person (e.g., Marta, Guard, Warden). This results in the wrong actor being credited in certain episodes. The transcripts will be updated to Marta 1.0/2.0 Warden Buck/Gentles, Guard 1/2, and so forth, and actor information should then be correct.
Thanks for bringing this problem to our attention!
