You need to import existing series instead of adding them as new series, at this point you can either update the path by editing the series or remove and re-add the series. Sonarr won't automatically link the series when importing if the year is not part of the title on TheTVDB, this is due to how TVDB's search works and something we will be addressing in the future.
Could be any number of reasoning, Sonarr's
Activity: Queue will give some idea why it's not importing (hover over the icon on the left). As will debug logs.
You'll need to check the logs to see why it's failing to connect, but it sounds like Sonarr failed to connect to uTorrent so it disabled it temporarily (Testing forces it to try again immediately).
