Ubiquiti UCI Nextgen X2 only 40Mbps Upload

I upgraded to the Nextgen X2 last week and upgraded my cable modem to the UCI this week. I am getting the expected 2.3Gbps download speeds but I am limited to 40Mbps upload. The cable is directly connected to the modem, there are no internal splitters or filters. I am not sure if there's a signal issue or a provisioning issue. Any help would be appreciated.
