I am trying to edit Mp4 tags and it indicates it is saving, but in reality it is not. In fact, existing Movie Titles are removed. Am I doing something wrong or is this a bug. the MP4 files are h.264 with AAC and Chapters. What is working is the Folder art import, but none of the other fields are working
