Two questions about sen2cor

Hello all, after I computed the L2A data via Sen2cor command line interface.Two problems were encountered:
(1)I open the image in RGB image window.It display as follows.
(2)The spectrum view seemed wrong,even divided 10000.
Does anyone can help me? Thank you for help!

For my Opinion,
It seems that you re looking pixels with snow? If the answare is yes, i think these values are logical, cause you haven’t remove the effects for the near pixels, that they propably are full of snow too, so they reflects a lot and they affect the signal. Also you dont know anything about geometry, so the atmospheric correction is 1-D, no 3-D.

If this is not snow, something is going totaly wrong.
TOA Reflectance values must be bad too, as like as in my pictures.
