Not getting 2gig speeds with UCI

I'm getting only 2.07Gbps download but only 20Mbps upload on my new "Next Gen Tier" modem of Ubiquiti UCI that I had installed last night. I'm on the Gigabit x2 plan. I am using a 2.5GbE port on my UDM-SE.

Ubiquiti UCI is a certified Next-Gen Mid-Split modem. I believe I am currently provisioned on a legacy bootfile capping my upload at 20 Mbps. Can you please push the Next-Gen / Mid-Split Gigabit x2 bootfile to my modem so I can get my plan's full upload speed?

Thanks!
