adding fields to JResearch & importing bibtex files

[M. A.]

Greetings!

I pulled the latest J!Research build from git. I'm still getting the Call to undefined function split() when I try to upload a bibtex file. I'm using php7.3

The other question is adding fields. My researchers have multiple job titles, their academic appointment, their title within the research group, and their hospital department appointment. We also don't use titles, but rather their degrees. Since we don't want the degrees appearing in the publications, I store them in a separate field.

I've added the fields to table _jresearch_member

I've added them to 

administrator/components/com_jresearch/tables/member.php

administrator/components/com_jresearch/models/forms/member.xml

I added them to the array in:

administrator/components/com_jresearch303/views/member/tmpl/default.php

When I try to edit a staff page, I receive Too few arguments to function JResearchAdminModelMember::save(), 0 passed in /var/www/itasite2018/administrator/components/com_jresearch/controllers/staff.php on line 266 and exactly 1 expected 

Any suggestions?

thanks!
