Query contracts is not initialized in AX 2012 SSRS

Hi,
I have duplicated LedgerJournal Report.
Accounts Payable > PaymentJournal

Duplicated below objects

LedgerjournalDP
LedgerJournalContracts
LedgerJournalController and businesslogicfiles.

I renamed all places where ever I want.

I generated CIL(both)

When I run the report Query contract object is not getiing initialized.

Classes\Srsreportruncontroller\getdatacontractinfoobjectsinternal
queryContracts = reportDataContract.parmQueryContracts();

If I am linking the standard menu item I am getting query in above line.

May I know the reason.I am getting the same Issue when I am duplicating the standard report.

Still controller class is pointing to ledgerjournal rdp and ledger journal contract eventhough changes are made in duplicated class.
