Repetitives thumbnails BUG for all my audio files

Hello.

Since a few days, the thumbnails for all my audio files are ALL THE SAME :



This is the same error on Yamaha MusiCast and with Hi-Fi Cast, both using DNLA.

I upgraded to Serviio 2.0, and this problem persists.

How to fix this please ?

Thanks.

there may be an image (the one you see) file in the folder where your music files are. It might be hidden.

I checked this, but there is not.

I upgraded with version 2.1 : same bug.

I even removed from the folder the mp3 file containing this image, and all the titles have always this same cover ??!!! Incredible.

I suppressed the folder in Serviio, then recreated it. Same result. Like there was a cache.

Is there a folder where the small thumbnails of the music files are stored ?

Thanks.

[EDIT] : the only solution i have found is :
- Remove in Serviio console the bugged folder.
- Create in Windows explorer a new folder.
- Copy the music files into this new folder.
- Delete the old bad folder.
- In Serviio console, add the new folder
