I can't get the DPI to work. I keep getting "DPI data is missing Please verify the DPI feature is enabled and that the Gateway firmware version is 4.3.38 or newer."

I can't get the DPI to work. I keep getting "DPI data is missing Please verify the DPI feature is enabled and that the Gateway firmware version is 4.3.38 or newer." and "UniFi Security Gateway Required Please connect a UniFi Security Gateway to enable the historical Latency and Throughput Charts." Everything is working fine. I just installed EdgeRouter Lite setup as WAN+2LAN2 where eth0 is my internet port, eth1 has my AP Pro and eth3 my DVR camera system. I don't have any switches connected and I don't have any USG.
