can't move note columns in both voices at beginning of a bar

[Stefan Thomas]

Dear community,

the following example shows, that I can't move NoteColumns in two voices at the beginning of a measure. It's only possible in one of the voices.

Has someone an idea for a solution?

Thanks,

Stefan

\version "2.18.2"
makespace = { \once \override NoteColumn.force-hshift = 11 }

First = {  \makespace e4 r8 f8 g2 }

Second = {  c4 r8   d8 e2   }

\new Staff { \transpose c c' << {  \First \First  } \\ { \Second  \makespace \Second } >> }
