I reported this two months ago and today I went back to a score that showed it, and the problem is still there. Here is an example file. Whenever there is an “Oo” vowel, not ‘Oh’, Muse Choir fastens on it and reverts to it at the next note without a lyric, whether tied or extended by underscore. A workaround is to add an invisible ‘Ah’ lyric but then the underscores are invisible too.

I tried to report this at 'Customer support' but the form did not work.
