Budget Transfer increasing the Senders Available Amount

Dear All

I have a situation like. we are implementing Funds management module with BCS as budgetary tool. On doing budget transfer using the Transaction Code: FMWA, the budget transferring is taking place. But on Report FMRP_RW_BUDCON, for the sender the transferred amount is getting increased in the Available amt column and for the Receiver the transferred amount is getting reduced in the Available Amount column

Thanks
