I honestly don’t know how I got here, because this piece has been in progress now for several weeks, but I wanted to show you something:
Obviously the top slur (orange) is selected and the others (blue) are linked to it. But while the upper two are only go to the end of beat 3 in the measure, the lower two all the way to beat 4.
It might well be, that I did some editing (insert? remove?) on some or all of these 4 staves, but I feel that Dorico should eighther keep the linked slur reaching to beat 4, or not keep all the slurs linked…
