No spatial reference system and wrong pixel size on Level2A images

Dear community,

I have ran sen2cor on Level-1C images and I have obtained all bands in Level-2A but non-of them have spatial reference system and when I define a geographic reference system using ArcGIS, the pixel size is 1m x 1m. Does anyone know why I don’t get the correct pixel size? This is Band 2 10 m resolution

I have also ran sen2cor on images of 2017 and all bands have reference system and the cell size are correct.

Thanks in advance
