Increasing the AGC gain during low power

I'm trying Fast attack AGC (Full table) on ad9364 with the help of IIO osc application. I feed the signal from SFU broadcast test system to the Rx port. When I increase the signal power level from SFU, I'm seeing the overload occurring and AGC jumps into the action and decrease the gain. But when I decrease the input level, the hardware gain isn't increasing at all. I even enabled AGC gain increase if signal below Low Power threshold and put Low Power threshold to 35 dBFS. I also put "if signal power decreases below lock level by "  to 4dBFS, still when I decrease the signal power level the AGC isn't increasing the gain. Is there any parameter that I missed out?
