Sen2Cor did not process Band 1 and Band 10

I applied the sen2cor processor on a Sentinel 2 image and post the processing two bands, band 1 and band 10 were not available.

I ran the following code

L2A_Process.bat --resolution 10 C:\Users\Sentinel\S2A_MSIL1C_20171015T044751_N0205_R076_T45RVL_20171015T045632.SAFE

I want to know what causes this issue. Is it the issue of sen2cor. How to fix it ?

That’s because the 60m bands are not considered when using the 10m resolution option.
I think you need to run it again with 60m option to get the missing bands.
