I found 2 posts on the community feedback talking about this same issue. I have tried all the solutions, like deleting and recreating fields etc., but no matter what I do the ISRC WILL NOT SAVE. I am using the ISRC_Editor to make sure it’s “embedded” in my wave files, but for mp3s i need to use mp3tag.
Why won’t it save? If it’s in the left panel I put in the ISRC and press save it disappears. If I have the mp3 selected and edit the column field, after I press enter the value disappears… Super frustrating!
