Maternity Reimbursement

Good day, late ko na nakita nag email si sss about my maternity reimbursement then meron dyannsa attached photo na "click here" then pag pumupunta ko sa portal no submitted maternity reimbursement. Na expired po ba since ang nakalagay is need ko ma confirm ang receipt of advance payment not later than may 20? Need po ba irefile ulit ni employer? Thank you sana may makasagot
