Album art error on player

Since it's translated, it may sound strange, so I'll write it in Korean.
I modified the album art of several songs to be different, but the file itself shows as changed, but when I play it, only one picture appears. Please tell me how to fix this errorโ€‹:smiling_face_with_tear::smiling_face_with_tear:

If MP3tag shows the picture correcty, then there is little that MP3tag can do about the display on the player.
You would have to investigate how the player likes files to show individual covers and perhaps you also have to find out how to update the player's cache or database if there is any.

Some players only show 1 cover art for each track of an album, no matter of there are different pictures in each track embedded.
Do these tracks belong to the same album and do they have the album-tag filled with the name of this album?
