When attempting to draw slurs from a whole note in one measure, to a stem-down note in the next measures, the slur always ends up shaped like a "U" rather than as an inverted U as it should be.
After selecting the slur from the green toolbar, you can use Setup/Draw to force the slur above or below the notes. After drawing a slur/tie, you can select it and change the position with Setup/Properties or right-click in the Consort Edition. There's more in the help file.
