Lost information in subset

Hi all,
I am trying to do a subset with SNAP of a S2 L1C image resampled to 10m. It works fine but in the output doesn’t appear the information about masks. Could anybody help me?
Thanks in advance.

Gonçal.

This is not working at the moment. Thanks for reporting, I created the issue SIITBX-183

Thank you very much, Nicolas.
