Unable to Get Corsair Fans to Sync with iCue

Howdy everyone! I'm having some trouble with getting my RGB to function properly; I've reviewed Zetty's Corsair RGB Hardware Guide, as well as the guide specific to my case (570X). But, I still cannot get my RGB to function properly.

Currently, I have the following setup:

Commander Pro:

LED 1: RGB Hub #1

LED 2: RGB Hub #2

FAN 1: SP120 Pro (Fan 1)

FAN 2: SP120 Pro (Fan 2)

FAN 3: SP120 Pro (Fan 3)

USB 1: H100i Platinum RGB

RGB Hub #1 (all three fans are on the front of my case):

Slot 1: SP120 Pro (Fan 1)

Slot 2: SP120 Pro (Fan 2)

Slot 3: SP120 Pro (Fan 3)

RGB Hub #2 (this single fan is in the rear):

Slot 1: ML120 Pro RGB (Fan 4)

In iCue, the following items are seen and work:

H100i Platinum: The AIO and the two fans are both seen; however, only the AIO and the aft fan can be changed; the front fan remains white no matter what.

Vengeance RGB Pro: Not necessarily applicable, but I can change the color just fine here.

Commander Pro: Fan 1, 2, and 3 performance is seen (all my front fans). For Lighting Setup, I have "Lighting Channel 1" set to three SP RGB Pro Series fans connected; "Lighting Channel 2" set to one ML Pro RGB Series Fan connected.

My rear ML fan's LEDs work perfectly! Obviously I don't see any performance because I don't have it plugged into FAN 4 on the Commander Pro, but that's not the big issue here.

HOWEVER: none of my three, front, SP fans will light up! They all work, but none of them have LED functionality.

Can anyone help me out?
