I do have ignore deleted episodes, however, I’m not deleting them but the ‘monitor’ flag stays on for episodes that have already been grabbed and downloaded till it grabbs the following one. Yes I understand that future setting applies ‘starting’ ‘from’ the moment it is set but episodes that have already been downloaded, checked, scanned, and verified by sonarr should no longer continue to be monitored at least by my logic since seven days ago no longer applies to ‘future’ or ‘present’.
No they do not stay monitored forever because sonarr monitors the episode it already downloaded till the following episode is grabbed and then automatically removes the ‘unmonitor’ flag from the previous episode. At least that is what is doing to some of the series that I have noticed.
So to summarize my understanding and excluding the enabling of the ‘ignore deleted’ setting or manually unmonitoring, then sonarr considers a ‘future’ flag till the next future episode is grabbed then sonarr now considers the previous episode as a ‘past’ and changes the flag to ‘unmonitor’ since it is no longer considered ‘future’.
Below is a screenshot of a perfect example: ep-06 was been ‘monitored’ for the past seven days while it was in that folder untouched and sonarr just changed it to unmonitor after it grabbed ep-07 a short while ago (it shows yesterday since it is after midnight here).
