MPK Mini Mk3 Knob not recognized as MIDI inside DAW

[BulldogCatP]

Hello!
While running Voltage Modular as a VST plugin inside FL Studio 24.1, I could not make my AKAI MPK Mini MK3 knobs 1-8 to work properly.
Although the DAW recognizes the knob tweaking, the VST doesn't seem to (the MIDI light doesn't trigger red while moving them).

While running Voltage Modular by itself, it actually works properly.

Can anyone help me, please?
Thanks in advance!
