What If Issue with mothers surname in passport (re-issue) ?

Hi My name is Farhan I applied for a passport in 2017 and it got approved with my mother's name written on it as 'Rukaya Akhter.' It was then mistakenly written with the surname 'Akhter' However, all my subsequent documents (10th certificate, birth certificate, and 12th certificate) only mention my mother's name as 'Rukaya' without her surname 'Akhter.' On the contrary, all of my mother's documents include her full name 'Rukaya Akhter.' Now, I'm applying for a passport reissue to remove the ECR (Emigration Check Required) category. However, the passport officers informed me that they can't proceed because my date-of-birth certificate doesn't include my mother's surname 'Akhter,' while my current passport has her full name. They suggested either adding the surname to my documents or removing the surname from my mother's documents and providing those to them If i had not passport and apply for new then there was no need of mothers doc Pls help me
