Incorrect song title for m4a files

I’n new to Volumio and so far I’m pretty pleased. The only problem I have is that the titles of all my iTunes m4a files aren’t identified correctly. All m4a files have “unknown” titles. Any other files have the correct titles. Any ideas how to fix that?

best regards

It’s a bug. I asked the same question last month and got no response yet.
