Title slug in use error: Stillwater (2020) vs Stillwater (Upcoming Prime)

Sonarr version (exact version): 4.0.17.2952
Description of issue:
I am getting a “Title slug in use” error when trying to monitor two different shows named “Stillwater”. I added the 2020 animated show first, and now Sonarr throws a slug conflict error when I attempt to add the upcoming Prime version. Could a moderator please apply a duplicate slug override on Skyhook?

Show 1 - Stillwater (2020):

Show 2 - Stillwater (Upcoming):

Thank you for your help!

The series title on TheTVDB needs to be updated for this new series to include the year, per their rules. It will also avoid failing to match based on title because they are the exact same title.
