Multipe times the same tracks with the old names after sync of a newly tagged music

After making new tags to albums and music tracks with Mp3Tag or Metadatics, completely erasing the old synchronisation and establishing a new one I got the same tracks multiple times with the old names-altough changed- and the new ones. However, the original tracks are not multiplied
What can I do to have only the actual ones?

Hi @gunther,

Do you have this with whatever type of tracks like MP3, FLAC, etc?

I use only wave tracks.

When you made the change in the tracks using your metadata editor, does Audirvāna was opened?

That’s a good question. I guess it changes. Sometimes I listen to music while I change the and sync later, sometimes Audirvana is closed.

Ok, can you please make a test while you edit a track with MP3tag and you have Audirvāna opened and a second one without Audirvāna opened?
