Lyrics under grace notes won't save.

Hi,
I'm writing drum notation. When creating flams, I use the proper grace note and then tie it to the main note(there should be an easier way to make a flam). To put the sticking underneath, I use the lyric function. It saves the letter underneath the main note of the flam, but not underneath the grace note (see attached). I'm using musescore 1.1 on a mac osx 10.7. Any thoughts?
THanks,
Mike
