Dear Sirs,
as You can notice in the attached image, "reference" and "URL" metafields have the same content, and I am not able anyway to hide "URL". Also, I tried to "send" it in the "Advanced" hidden portion of the page (advanced=true in config.json) but that field is still there over the "reference" field. look like it is a standard field (like reference, title, summary, database)
Is there a way to move/hide such a field?

I attach my config.json, too
thanks v.m.
config.json.txt
