when youre looking at the page for a series that yes/no choice can also be set by clicking on the the monitored icon/action in front of its name (the bookmark/flag looking icon). it toggles between monitored (filled in) and unmonitored (hollow)
as well as the series name theres a monitored status icon/action next to each season and each episode.
- clicking on the monitored icon for an episode will toggle the status of that episode
- clicking on the monitored icon for a season will toggle the status of that season, and sets every episode in that season to match it
- clicking on the monitored icon for the series will toggle the status of the series. it wont set them all to on or off like the season setting though, it just disables/enables the ability to set the season and episode status
you can click each of those icons in any combination you want to get it to match those seven original options
