Name Spelling Error on sage payslip portal

SUGGESTED

Hi someone has brought to my attention that their name 'Lynette' is spelt wrong on her payslips via the online sage documents portal. I have changed it to 'Lynnette' with 2 'ns' on sage payroll, but on the online documents it is still the wrong spelling. I have deleted her from the portal and re-added her but its still the wrong spelling - how do i change this??
