I’ve just tested this again, with the same example, and it seems to work fine. You do still have to click on each of those horizontal line segments, and delete them individually.
If it’s not working, perhaps the paths were not combined successfully. If those paths have been combined, then you should be able to click on the combined path (once) and then be able to click and drag it. Also, when it is selected, the status bar at the bottom of the screen should read “Path (84 nodes) in Layer 1.”
