Punjab National Bank Housing Finance [Pnbhfl] — issue of pmay subsidy

We taken home loan from PNBHFL bank, on resale property, on 28 may 2019 .
But problem is that PNBHFL bank demanding loan statement from first owner(seller) of that flat who taken home loan from LIC bank on 2011, TO confirming is PMAY subsidy Gave to first customer(seller) or not on that flat which one we bought on May 2019.

so i want to know This resale flat is my first home so PMAY subsidy is applicable if yes so why PNBHFL bank ask loan statement of first owner?
Their is no any consult of first owner who sold this flat to us .

My request is to kindly pay attention on this matter and give me advice what to do.

My PNBHFL reference no : HOU/NSK/0319/671727
