I didn't got this error. Loading of authority record and bibliographic record
worked fine for me.

Yes, normarc should be removed.

This is actually correct, because the fourth Feminism term has second indicator
4 which means "Source not specified". So this term is only a local term and
does not belonging to any specific thesaurus and thus not linked. To specify a
source of a term, second indicator must be 7. The source of heading is then
specified in subfield 2.
