SLSTR Oblique data fail in "radiance to reflectance"

Hi all,
I’m using Snap 6.0 switch SLSTR radiance to reflectance, with the “Radiance-to-Reflectance Processor” function.
The problem is that a part of oblique reflectance data(S1-S6 band) is missing compared with radiance data:

Can someone explain with this problem?

Thanks

The Radiance-to-Reflectance Processor has been designed to work with SLSTR L1B products at 500m. When you open the product in SNAP Desktop, choose to read at a 500m resolution. The processor should get you the correct results then.

Thank you very much.
But the oblique view was still like the picture above while nadir view was correct.

This is a bit weird, as I got the result in your first post when I read the bands in its native resolutions, but got the correct result when I chose to read in 500m resolution. I attached the different results: Native resolution is up, 500m resolution below. Can you switch on the no-data-layer and say which one yours does more look like? Or post another screenshot with the no-data-layer when yours looks different?
