The following quote from the contribution bible is a little unclear: "Only crew members that are credited in every single episode of a season should be added to the crew at a season level".

Do you mean, only credits given to crew members in every single episode of a season should be added to the crew at a season level, or do you mean, only crew members that are credited in every single episode of a season, regardless of what role(s) they're credited for, should be added to the crew at a season level?

For example, Justin Berns, is credited in every single episode of season 1 of The Gay and Wondrous Life of Caleb Gallo, however not credited for the same role. He is credited as the executive producer for ep. 1-3, but as the producer for ep. 4 and 5. Technically this crew member is credited in every single episode of season 1...should they be added (as producer and executive producer) to the crew at a season level? Or should the credits be added on the episode level?

EDIT: Unless I'm missing something, I personally think that should be made clearer in the contribution bible.

EDIT x2: For now, I have added Justin Berns' credits on the episode level.
