Problem with Roon ARC exploring library folders

Hello,
when I explore my library folders with Roon ARC, I have problems with the cover pictures.
In my folders, the names of the cover pictures are all front.jpg and back.jpg.
For instance in my folder Diapason (745), the file front.jpg is :


But when I explore this folder with Roon ARC, if I click on the front.jpg file, it shows another cover :

This picture is in another folder : Diapason (749)

Thank you for helping me.
Best regards,
Sylvain Renard

Hello again,
in fact the problem does not come from Roon ARC but from the application which shows the pictures on my phone.(MI browser).
If you have the same issue, empty the cache memory of the browser.
Best regards,
