20.7 Beta 3: Patcher/VFX Key Mapper Issue

[Xaos]

I have been looking at some audio projects done with the powerful Patcher and they are really good and Patcher seems to handle them very well.
Now, another thing is when it comes to handling MIDI flow.
Maybe I find some logical operators missing, like AND, OR conditions, etc, but thanks to some users, I have found different ways to handle these situations by using different modules like Fruity Keyboard Controller, Fruity Formula Controller, VFX Level Scaler, etc.
So, I have decided to make an ambitious project, for me, to be able to select different musical scales by using the low octave keys.
So that, the keyboard would be split into 2 sections, the lowest octave, where I would select the scale, key C0--> Major Scale C, key C#0--> Major Scale C#.
And the rest of the keys in the upper octaves would be used to play the notes according to the selected scale.

However, there is no way to get past the first step.
I've tried it in different ways but I always stumble upon the same stone, and that's because when 2 or more VFX Key Mapper modules are connected in parallel, the behavior of this module becomes erratic.

As my knowledge about Patcher is quite poor and I don't know the limitations, it's possible that it's my fault that it behaves this way, but no matter how much I look at this issue I don't see any other reason than some kind of bug in the VFX Key Mapper module, or the combination of the modules used for this example.

For this, I put the project here.
If you play it, you can hear the whole sequence of notes in the C Major scale, since the C0 key is selected in the lower scale.
If you now go to Patcher and connect the MIDI input to module B (C# Scale) as well, nothing should happen, because the key C#0 is not selected, but the Module A (C Scale) will stop playing some notes in the C scale (!?)
