Kodi 17 discover error for TV Show

Hi
After migrating to krypton I am no longer able to enter TV show in the database.
It appears in the error log;
ERROR: ShowIMDB: could not add episode [/ media / O_Store / MOVIES / TV Series / The Flash S03 / The.Flash.3×06.L.Ombra.ITA.ENG.DLMux.XviD-Pir8.avi]. tvshow does not exist yet ..
I tried using different providers (eg TVDB and The Movie Database) but the problem persists.
can someone help me?
Thanks Marco
