When you enable 'Add New Episodes (to My List)' for a specific series, SHOWTIME will add that series to your 'Series Manager'. Here you can disable this feature and keep track of other series that have this feature enabled. To stop new episodes of a series from automatically being added to 'My List':
- Open 'My List'.
- Select 'Series Manager'.
- Find the series you want to remove and click on the trash can icon or choose 'Remove' from the list of available options.
