AD 9364 LO leakage and quad calibration failure?

I have configured 9364 filter chain as per .ftr file attached.

 

After successfully configuring the device when I read back register 0x0A7, it gives 0xEB which shows LO leakage algorithm and quadrature calibration algorithm converges.

After this I run below given command via UART console:

tx_fir_en=1

and then

rx_fir_en=1

 

Again when I read back register 0x0A7, it gives back 0xFC which shows that none of the calibration and leakage algorithms converges.

What is causing calibration failure?

 

I have attached whatever console window of CCES IDE outputs during the configuration process.

I have also attached default initialization parameters of my design.
