Name issue in sale deed and rectification deed

Hello Sir, I am planning to buy one of the property ,it is Karnataka housing board(KHB) property. Current owner is owning title post transfer of ownership from first allottee to him There was some issue in dimension of property in main sale deed made b/w KHB and Allottee so rectification deed was made to rectify the changes ,note rectification was made directly by KHB to Current owner without presence of allotee as current owner states it was not possible to trace the Allotee as he was 87 at the time registration which happened in 91-92 and he might be dead now. Is this rectification valid ? Now i see one more issue,sale deed made between current owner and allotee in 91-92 was in local language Kannada which contains owners name in kannada but rectification deed is made in english Issue here is name of the current owner in Sale deed was ಮಹೇಶ್ (which means Mahesh in english ) so in rectification deed which done in english name of owner is stated as Mahesh, but in all government proof which currnet owner owns name is english is seen as Maheesh . So wanted to confirm if it is acceptable by just taking Affadavit,
