Sonarr refuses to import a handful of episodes

Hoping someone can help I have recently done a full media server rearrange and sort out and as a result I decided to make things neat and tidy I would re-import all my shows as they used to be managed by a different app before I moved to Sonarr.
But for some reason its refusing to import a few episodes from random shows, I have found a load of duplicates witch I ended up with and got rid of them but am left with 8 files that are showing as missing episodes but just wont import dispite me actually having them.

I looked at the logs and found this for a couple of them

System.InvalidOperationException: Sequence contains more than one element
   at System.Linq.Enumerable.Single[TSource](IEnumerable`1 source)
   at NzbDrone.Core.Parser.Model.LocalEpisode.get_SeasonNumber() in m:\BuildAgent\work\6c3239faf2b92630\src\NzbDrone.Core\Parser\Model\LocalEpisode.cs:line 25
   at NzbDrone.Core.MediaFiles.EpisodeImport.Specifications.NotSampleSpecification.IsSatisfiedBy(LocalEpisode localEpisode) in m:\BuildAgent\work\6c3239faf2b92630\src\NzbDrone.Core\MediaFiles\EpisodeImport\Specifications\NotSampleSpecification.cs:line 27

But the others just don’t even get looked at theres no .ignore file or entry in the log for them, how can I fix this?

Whats the path for the file its trying to import and which series?

((Debug logs)) will tell you why the others are not importing.

lol I figured it out after all that, turns out that my auto converter had failed to fully convert the videos in question so I had files ranging from 35-81mb due to this sonarr refused to import them as there were not the right size and it thought they were samples
