Razer PWM auto mode not responding to fan curve

I have 6 Razer Kunai set up to the fan controller, which is detected and can be set manually in Synapse both 3 and 4.

I ungraded to Synapse 4 in hopes that this issue would be resolved, however it hasn't been.

I can set the curve to literally anything but the fan speeds only change when set manually. Somewhat frustrating but I've been making due with inter-device keys on my keyboard to quickly switch from quiet, normal, and performance.

“DC connection” not popping up, just straight up ignores the fan curve optimizer.

I would like to mention I have uninstalled, and removed all Razer related entries in my Registry Editor before doing a clean install through the link on their website. This is the most common way razer support tells me to “fix” anything but it rarely ever works.
