Mixer faders midi learning doesn't work

[PxBCPG]

Describe the bug
I can't assign a midi control to the mixer faders

To Reproduce
Steps to reproduce the behavior:

1. Go to the mixer
2. Click on map, the faders and your midi knob
3. In the mapping section, it doesn't map it to a fader but instead to the last midi learning I made on other stuff (eg. on my synth or something else)

Expected behavior

The midi learning feature doesn't work here.

Standalone (didn't tried with plugins)

Additional context
None

MIDI mapping works with plugin parameters. Faders are not a plugin. I do, however, want to extend learning to more than just plugins.

That would be awesome! Because right now I didn't found simple mixer plugin like that one and the only solution to "mix" is to midi map every volume knob of every device (that doesn't have the same velocity curve so...).
Hyped to see this feature come true!

Oh and by the way I'm talking about the mixer "plugin" (even it's not a real plug-in one 😉 ) in case of misunderstanding.
Here are some screenshot of what I mean:
