Split because this is not the same issue (the other thread indicates Sonarr did not grab the episode multiple times).
It should, tough to say why it didn’t (or if they were remonitored somehow).
We’ll need some more information to investigate further:
Sonarr version (exact version):
Mono version (if Sonarr is not running on Windows):
OS:
Also if you could PM me a copy of your database I want to check a couple things on the series to see if this is something we’ve run into before but haven’t pinpointed the cause.
