FLAC - all files under unknown artist (unknown album)

I purchased the Clip Sport in September of 2014.  The support for FLAC is lacking.  FLAC files will play, but they do not show up properly under the Music menus.  This behavior is the same whether the files are Internal or on the External card.  They do not show up properly unless I select the Folder menus.  But that is because I have the files laid out under the Artist, then under the Album.  Under the Music menus, they show up under ‘Unknown Artist’ or ‘Unknown Album’.  This is a definte problem as FLAC files work as they should on the Sansa Fuse that I also own.

Support for mp3 and m4a/acc files work properly.  But, they are lossy, whereas, FLAC is lossless.

I have edited the tags as described in another post, but this has not worked.  Hopefully version 1.18 of the firmware will fix this issue.  I am currently on version 1.17.
