Default Strange chassis fan behavior

My 4 chassis fans are connected to the Phanteks Evolv X fan hub. On the hub the first fan pin connector detects the RPMs of all the fans connected to it. This first fan spins at a different speed. This behavior goes away if I go into fan Xpert and run them at full speed then back to standard. At first I thought it was the fan but then swapped some fans around and its always on that connector that detects the speeds. Anyone ever experience anything like this? Could this be an issue with the fan hub?

Are all the fans the same or is the off-speed one a 3 pin while the rest are 4?

Looks like you're not the only person experiencing issues with 1 fan on that hub.....

Does your motherboard have the ability to set either DC or PWM?

Seems like their fan doesn't work at all when connected to that white PWM header.

Yes I can can select either PWM or DC. The fans are automatically detected as PWM.
