Warning in radiometric calibration in Sentinel-1 COG

Hi everyone

I am trying to perform a radiometric calibration on a Sentinel-1 COG image and I get the following warning:

"The calibration LUT for this product could be incorrect and therefore the calibration result may not be reliable”.

"I have performed the calibration on the Sentinel-1 COG image and on the same Sentinel-1 image but not COG (both images were downloaded from the Copernicus Browser), and the results are different, so I assume that the calibration on the COG image is not being done correctly. Could you help me solve the problem?

I am using SNAP 13

Thanks a lot
