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

Address:	411041
Website:	mahadbt portal

I have linked my aadhar card with bank account but on mahadbt site (New site for scholarship) 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 (Central 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.
