WHY! are you using Get ISBN on a EPUB? They were published with the correct one in the books metadata.
The plugin (my interpretation) was mostly for PDF and other documents that do not have well defined metadata (identifiers)
As you discovered, you run the risk of corrupting valid metadata.
FWIW My Service number was 7 digits: nnn-nn-nn then some idjut decide stenciling my SSAN all over my gear was a brilliant idea
