Slurs Not Transferring to Condensed

Dorico
#1

For some reason the slurs in the original Flute 2 are not appearing in the condensed version.

P.S. Any way to hide the rests in the second flute (for example) when not playing?

Try selecting everything on the Flute 2 stave and changing it to Upstem Voice 1. Condensing works on the assumption that everybody’s always on Upstem Voice 1, as far as I can tell.

Thank you, Leo. That was the solution.
