National Payments Corporation of India [NPCI] — Aadhaar not linked with bank account for scholarship form

Address:

1001A, B wing, 10th Floor, The Capital, Bandra Kurla Complex Rd, Bharat Nagar, Bandra East, Mumbai, Maharashtra 400051

I have linked my aadhar card with bank account but postmatric scholarship scheme it displays that my account is not linked with aadhar card . My college staff suggested me to fill form of npci mapper which will be available in banks, but when i visited my bank ( State Bank of India) they were not knowing any concept of npci mapper and they just gave me confirmation that my account is linked with aadhar card. I want to fill my scholarship form as soon as possible . So please help me and obligue me.
