AD9361 RSSI Reading issue

When we read the RX RSSI from AD9361 from board, the RSSI is calibrated and all the path Gain/Loss are counted in, we expect a power accuracy within +/- 2 dB, but sometimes it is up to 4dB away. What could cause the error of the RSSI reading? Could it be the software or the AGC?
