Sentinel-1 co-registered stacked data fails to export to PolSARPro format

Sentinel-1 co registered stacked data fails to export to PolSARPro format. It just output the config.txt file.

If we try to save to PolSARPro format in the output (Save as) of the S-1 Back Geocoding it gives the error “The name “Master: 12Jan2023” is not legal for JDOM/XML elements: XML ‘Master: 12Jan2023’ CANNOT CONTAIN THE CHARACTER “ ”.

I think it is related to the blank space in the metadata data name, but that name is created by SNAP when using S-1 Back Geocoding.

Any help will be really appreciated.
