ERROR: Cannot Update DDC, LCC for Selected Books
Sorry if I am being a bother I am receiving this error:
calibre, version 3.35.0
ERROR: Cannot Update DDC, LCC for Selected Books: An OCLC-OWI Identifier for at least one of the selected books, plus DDC and/or LCC Custom Columns, must exist in this library order to perform this action.
I don't understand why I would since I have the column present and added an OCLC number
Thank you in Advance, I apologize if this was addressed somewhere else I couldn't find it.
