i realized that Dianemo is double tagging mp3s.
i am using an external windows software for tagging the files.
if i - e.g. add an correctly tagged album to dianemo it looks ok.
If i change something for example Album to something else externally, than dianemo resyncs it, but adds the new album as a second album tag in each file. So the album tag is existing 2 times. and the album is existing two times.
Same is for all other tags.
Can you give me more detail on what tag your adding and where your adding it etc. Also send me privately an example of a track that you have tagged in this way please.
All the best
