Unable to read PICC frames

Hello all,

I do have proxy spy and RGPA installed on my machine. When I try to read the RF traces between PCD and PICC, I'm not able to see PICC frames being sent to reader.
I CAN only see PCD frames sent to PICC.

I used to see PICC frames earlier on this setup.

Could someone help me out ASAP?

Thanks.
