ID 583131 - Exporting multichannel audio using 'Process as Shots' results in duplicate export tasks

Problem summary
Exporting multichannel audio using 'Process as Shots' results in duplicate export tasks.
 
Customer reported version
Nuke 14.1v2
 
Customer reported platform
Windows 10
 
Steps to reproduce
 
1) Open Nuke Studio.
 
2) Import a .wav file (File > Import File(s)...) with multiple channels and drop it on to the timeline. It may be easier to see the problem if the left and right channels are different. For example:
 

 
3) Right click the audio on the timeline > Export.
 
4) Create a new export preset, like so:
 

 
All settings for the Audio Export can be left as default. The {track} keyword is used to ensure unique names, preventing any files from overwriting each other.
 
5) Click Export. You should then see that there are 2 separate export tasks:
 

 
6) Import the .wav files exported in step 5. You should see they are identical:
 

 
Expected behaviour
Nuke Studio shouldn't export duplicate audio files. Exporting the left and right channels should result in one .wav file with the correct channels.
 
Actual behaviour
Nuke Studio export two identical .wav files.
 
Workaround
Unknown.
