I have a simple question about the FLAC / Vorbis Comment tag.
Is it allowed that a "FLAC / Vorbis Comment" contains a tag field, which is empty?
In German: Ist es erlaubt, dass ein "FLAC / Vorbis Comment" ein Tagfeld enthält, was leer ist?
I have to ask because there is a FLAC file, which contains four tag-fields ...
... after applying the M3tag action "Import tag-fields (guess values)".
The four tag-fields have been created by the action "Import tag-fields (guess values)" using ...
Source string: "~
Mask string: "%ITEM1%~
(without the quotation marks).
I am surprised because it works differently than the MP3 tag.
When I open the dialog "Extend Tags..." and remove one of the two empty tag-fields, then both empty tag-fields will be removed at once.
It looks like a buggy behaviour in Mp3tag, but I am not sure because I do not know how Mp3tag works with the tags internally for MP3 and FLAC.
