There is an option to write the tags to the file. Try setting it.
1. If you are referring to options -> General -> Update tags when file info changes, it is checked. I have 6400 .ape files and tagging works
perfectly in keeping information as part of the file. It is only with a handful of .ape files, all fields are updataeble except for "year".
I took offending file to naother computer and again, "year" field could not be updated. I want to remove tags and try to redo tags
but that is not possible. See item 3 below.
2. I checked Help and looked at topic "Save Tags in Disc Files". Item 2 asks to check for each field, "Store in file tags (when possible)".
I did not find any field named "year" in the standard list. I did find field "year-album" and checkbox is greyed out and is not checkable.
Only audio box on left side is checked.
3. There does not seem be capability to remove tags even though Help topic says. Selected file in question, right clicked and
selected "library tools". There is no option to remove tags.
