[Koha] How do you import multiple patron attributes?

I have 6 extended patron attributes but only the first will show up after the import. My csv header looks like this: cardnumber, surname, firstname, address, city, state, zipcode, phone, branchcode, categorycode, dateenrolled, dateexpiry, borrowernotes, password, userid, patron_attributes Some sanitized sample data: 2903045,OWENS,BUCK,999 FICTITIOUS PL,RICE,WA,99075,(900) 999-999,LIBMAIN,STUDENT,05/22/2015,10/31/2021,ONLINE_STUDENT,pass,93,SCHOOL:MIDDLE SCHOOL,CURYEAR:2015,CURGRADE:06,SID:091,GRADYEAR:2055,TEACHER:SMITH Only SCHOOL shows in staff client. -- Chad Roseburg Automation Dept.
