Sage 300 Bank Transfer Issue

I have an issue that just started. I regularly use the Bank Transfer Function for when transferring funds between accounts. Usually a seamless process, you complete the transfer and then clear the transaction inside the Bank reconciliation under corresponding bank accounts. However what has just started happening is the withdrawal side comes through as normal and you clear and that account reconciles but when I go to clear the deposit side in the other account the corresponding transfer has come with with 0.00 instead of the actual value and it can't be cleared. Has any one experienced this at all and is there a solution for it?
