SNAP cannot display Landsat 8 iCOR processed images

Hi,
I am having trouble extracting pixel values of iCOR output for Landsat 8.

This is a screenshot from the SNAP. As you can see, the pixel info is weird, and there is no lat/long.

Here is the same image in ENVI:

Does anyone know the reason?

Thanks.

PS: I am using SNAP 8.0 and iCOR 3.0.
