Export Multiple does not work for anything other than the first track

Linux version: Xubuntu 17.10, kernel 4.13.0-46-generic x86_64

Synopsis: Export Multiple does not work for anything other than the first track.

I have a project with multiple audio tracks. Each audio track has a label track underneath it. I would like to export audio to FLAC for all tracks, based on the label. So for example if I have:
Track T1
Label L1_1 L1_2
Track T2
Label L2_1

Then I would like the export process to result in three files: Track T1 audio for the timespan included in label L1_1 boundaries; Track T2 audio for L1_2, and track T3 for label L2_1. I don't want the audio mixed from across different tracks.

I go to File > Export > Export Multiple with the options:
* Format: FLAC
* Level: 8
* Bit: 16 bit
* Split files based on: Labels
* Name files: Using Label/Track Name

Then I get a metadata editor for L1_1 and L1_2, and as a result I get 2 files, not 3.

If I select only label L2_1 such that its audio is selected, and do the File > Export > Export Multiple again, I am prompted for metadata for the labels on T1 again.

How do I achieve what I'm trying to do?
Thanks!

Export Multiple will export one or more files based on "tracks" OR "labels".

When based on tracks, each audio track is exported as a separate file. Label tracks are ignored.


When based on labels, the labels in the FIRST (topmost) label track define the start and end times of each exported file. Each exported file is a mix of all tracks in the project, and subject to their Track Gain, Track Pan, and Mute button settings (muted tracks are not included in the mix.

As you are only wanting to export parts of three tracks, without mixing, it will probably be easier to use "Export Selected Audio".
