odd and even lyrics style should be applied when changing a style

Version 2.0.0 3969M Ubuntu 10.04
After import of an XML including 2 lines of lyrics, I apply a style sheet (there is some errors in the application of the style, one can correct them by modifying the style, and then setting it back)

however I found that the even lines lyrics style is not applied. (the odd lines one is applied to any lines).
I tried lassoing even lines, and applying the even lines style through the style windows of the contextual menu.....it did not work.

So I use some find and replace in the mscx file (I could explicit this way if anybody needs)
