Why when I repatriate FLAC audio tracks to a playlist from a USB key, do they lose their album art?

Yes, this problem is still not resolved.

I sent @ROSEHAN an email with a Google Drive link to two example FLAC files that are properly indexed and have cover art. When the two FLAC are added to a playlist, one of the covers displays correctly, but not the other.
I asked ROSEHAN to test this himself and provide feedback, but I haven’t received a response.

@ROSEHAN could you please perform this test on an RS130 and give me your results?
