[SOLVED]: Need for some help: double album entries in BubbleUPnP

[mf_im_fb@hotmail.de]

Hello,

maybe someone give me some advice how to get rid of double album entries in BubbleUPnp.

Where I am:
I've installed a containerized Mimimserver on a Linux server using Podman (comparable to docker).
For now I'm on the starter version for testing purposes.
I have a couple of hundreds of music albums baught and ripped; partly as FLAC, partly as MP3. Each Album is placed in its own folder on the filesystem.
I can stream music with no problems and I'm quite happy with the sound compared to minidlna.

What is the problem:
I see a double entry for most of the albums with exact the same content. I've baught quite a while back ADELE 21 and I can see 2 entries on BubbleUPnP.
Only a couple of days back I've baught Layers of Life from the Emil Brandquist Trio which is only shown once as expected.

What I have done so far:
I've been searching this forum and I came accross that this might be a problem with Id3 tags not correct set.
So I took ffmpeg / ffprobe for reading the Id3 tags, looking for some differencies and than correcting the Id3 tags.
Maybe I'm blindfold but I can't see any real differencies between those two albums.

Here's what I got for ADELLE 21

Code:

I'm sorry but I can't see any difference between within the data structure, only within the data itself.

So I don't understand what I'm doing wrong.

Any help to find a solution is highly appreciated.

Best regards
