Yeah, thanks for the report.
Diving back into the code was an opportunity to make some additional corrections in addition to the one you reported, so here the new version 0.12.0:
- Prevent to use 'Embed "authors (Authors)" column' at the same time that a a explicit contributor/column pairs that use the type "Authors"
- Previously, it silently disable it
- Improve parsing and reading of "dc:creator" tags
- fix: support multipe "marc:relators" for a single "dc:contributor" tag
