I want to create several smartplaylists to separate my audio files according to language. I have in the comment field of the metadata of my .flac files 3 letters for the language, for example "ïng" for English, "esp" for Spanish. I have created both lists to test and the English one, works but the Spanish one does not. I have verified that the metadata is correct in the files. I am using kodi version 18.6, I have tested it on both windows and android and it has the malfunction in both platforms. I have not seen anything unusual in the log (which I attach below), but nevertheless it does not work correctly. Can anybody help me?
