Mobile device warehouse transfer error

When processing a warehouse transfer with the mobile app emulator I get the following message, “Offset account is not specified.
Setup of ledger account for Inventory expenditure, loss is not specified.
Update has been canceled.”

If i try the same transaction with a transfer journal it works with no issue and I can also carry out transfer orders. The accounts look set up correctly and cause no issues for the transfer journal, only warehouse transfer sees this error, any suggestions? Many thansk
