Forward Loan contract End Term is already over. NPV becomes Zero.

What causes this issue?

The evaluation date is after the end date of the forward loan contract.
The forward loan contract has a value before the end date of the
contract. From the end date on, the underlying loan will become active
and will have a value. Hence NPV shows zero when the contract is
evaluated on or after the end date of the forward loan.
