No difficulty bars for the whole song

[DiversantBivnev]

Yesterday I've discovered that on some CDLC songs I don't see the difficulty bars, thus I get the 100% difficulty when I try to play a song.

As can be seen on the screen there are no bars at all. Quite odd. Never seen that before. What could be the reason? any fix?
