I noticed that one particular TV Series that I recently added (Foyle's War) has out of sync episode information starting about half way through the series. The files names are all correct, use SXXEYY and are divided correctly into multiple seasons. But halfway through season 3 there is no episode summary and the next season repeats the episode information from season 3. All subsequent seasons use the information of the previous season.
This may just be an error in the database that was used to import the information but since the series came out a long time ago, I assume this kind of error would already have been detected at their end. Is there any other explanation?
