[Koha] Authority error

[clint.deckard]

After installing Authority files downloaded from SCIS via the 
bulkauthimport script on 3.8.3 using Debian packages, I get this error 
when attempting to 'choose' an entry for the 100$a field;

Software error:

Can't call method "subfields" on an undefined value at
/usr/share/koha/intranet/cgi-bin/authorities/blinddetail-biblio-search.pl
line 86.

Other fields work without error.

Google the error has not been helpful, Would someone kindly be able to 
point me in the right direction.

Many, many thanks,
Clint.
