Value 0 in pixels L2A Level

Hello
After using Sen2Cor L2A_Process… --resolution 10 I
noticed that in bands 2 3 4 and 8 (10m) appears pixels with 0
VALUE. Resolution for 20 and 60 meters looks correct. Original picture
(Level 1C) looks good and doesn’t appear pixels with value 0.
Pixels appear in places where reflectance is high (eg. bare soil clouds or
early vegetation). Does anyone similar problem?

My problem looks like this (picture below)
RGB 432 10m

RGB 567 20m
