Exporting files with label-based names

In a v3.75 project I have three audio tracks, each with an adjacent label track. Each audio track has multiple clips, each with a distinct label. I want to export each clip in the project to a separate wav file, with each file’s name based on the clip’s label. However, when I try to do that using Export Range: Multiple Files, Split Files based on: Labels, and Name file: Using label/track name, Audacity exports only clips from the first audio track in the project,. This is regardless of whether I select only that track or select all three audio tracks, and regardless of each audio track’s Mute/Solo setting. How can I export clips from the second and third audio tracks ? I’m OK with either exporting all of the project’s clips at once or exporting separately from each audio track in turn.

Have you tried changing the order of track + corresponding label-track? If you move the second up to the top, it should get exported.
