How to assign audio tracks?

I'm feeding 8 audio tracks into OBS using JACK:

And in OBS I made sure to tell it to use 6 tracks:

Now I've done a test recording and extracted all 6 audio tracks using ffmpeg:

Code:
ffmpeg -i my_obs_recording.mkv -filter_complex "channelsplit=channel_layout=5.1[FL][FR][FC][LFE][BL][BR]" -map "[FL]" front_left.wav -map "[FR]" front_right.wav -map "[FC]" front_center.wav -map "[LFE]" low_frequency_effects.wav -map "[BL]" back_left.wav -map "[BR]" back_right.wav

And imported them into Audacity to analyze if every input track got written to its own output track:

But for some reason all input tracks have either been written to the front_left or the front_right track of the video file.

Any ideas how to fix that?
