QB Issue Resolution:
After alot of trial and error I actually found a solution myself.
From the bank feed, instead of matching payments to invoices, I added the transactions as a Cheque with the Payee as the relevant supplier and Creditors as the account to post to.
I then went into the suppplier and used the credits on the account to offset against the open invoices which left the correct credit open on the account to use against the next invoice.
