Filenames with years in them get detected as season numbers, for example:
Old filename: Dziga Vertov - L'uomo con la macchina da presa - 1929.avi
New filename: Dziga Vertov - L'uomo con la macchina da presa - [19x29].avi
Old filename: Batman.V.Superman-Dawn.Of.Justice.2016.EXT.ED.ITA.ENG.1080p.BluRay.x264-BLUWORLD.mkv
New filename: Batman V Superman-Dawn Of Justice - [20x16].mkv
Old filename: Al.Di.La.Delle.Montagne.2016.ITA-CHI.AC3-5.1.Bluray.720p.x264-iCV-MIRCrew.mkv
New filename: Al Di La Delle Montagne - [20x16].mkv
I suggest not to treat four consecutive numbers as seasons indicators.
