Yeah, I was in Sigil cleaning out tags that Calibre put in
And re-running Flight check. I only grab that section cause i did not keep the pre-clean file which had Calibre specifci tags in it that were label "Calibre". The point is I only, ONLY, put that meta data in Calibre, no place else. The Flight could not add those fields because Sigil and Flight check did not know that data. ONLY Calibre did.
