@zewker it must have assigned the same unique ID due to the title so some eps will have multiple files.
@IIGTRII tvdb2 mode would do that but if you rename the series folder name after a scan nothing will change since the folder content didn’t change and the scanner cache results (apart from grouping folders). You probably failed to do the Plex dance during your tests. Checking series specific scanner logs would also have confirmed if change was taken into account
@Bai_Shen check series specific agent log. At the end it will confirm the title used and which metadata source provided the title depending agent logs. The answer is definitely in there
