I've run into a strange problem that I think may be a bug. In this MWE, I have a repeat with alternate endings. However, the "\repeat unfold 3 { c1 }" is causing the volta brackets to disappear for some reason. If I instead write out "c1 c1 c1", it works as expected. If I add another note right before the "\alternative", it also works as expected. However, if there's a repeat right before the "\alternative", it messes up.
%%% \version "2.24.4" \fixed c'' { \repeat volta 2 { \repeat unfold 3 { c1 } % c1 c1 c1 \alternative { \volta 1 { d } \volta 2 { e } } } c4 r r2 } %%%
