Unable to Add Executive Producer to Series

Further to @Peter_pbn’s advice above (thanks), please see https://help.imdb.com/article/contribution/filmography-credits/how-do-i-add-an-episodic-credit/GRRHUZAQPQV4T2F9?ref_=helpsrall#multipleep  (the help works just as well for producer credits as it does for actors).

Thank you! I figured I was missing a step. So this sounds a little easier than having to submit separately for each of the 20(ish) episodes.  ;) I will go through the above steps, submit the same information, and cross fingers! Thanks again.

I resubmitted to include each individual episode as the above process suggests, which was easy to do. I do however still get this warning at the end, so wondering if I'm still doing something wrong. (But I submitted anyway and we'll see!)

This credit has warnings, you must acknowledge each one before this credit will be accepted.

   Warning understood, go ahead anyway.

• Carrie Lozano is already credited for Independent Lens (1999) in the Producers section
