Rx rssi no longer working?

I just made the jump from plane 3.8.5 to 3.9.9 and noticed that my rxrssi user-item on the MP HUD no longer works, its just zero’d. No change to my hardware setup or parameters. Using an x8r connected by sbus to the RC input on a pixhawk cube and have the rssi_type set to 3, RSSI_ANA_PIN=0, which worked before.
