Problem after calibration for TSX-TDX dataset

I am using TSX-TDX dataset in my project and the xml file is named as TDX1_SAR__SSC______SM_Q_DRA. It is a cossc product acquired in the month of december. In the image there are many NaN values. I dont know how to remove these values. I have also unchecked “NO DATA VALUE”.

Seeking your kind support and guidance.
