yes that is really a major failure, it's a transaction type that is associated with suppliers so should have been included in ALL transactions and should also be in the list of valid selectable transaction types.
Who at Not Intuit tested this or signed of the Repot Spec. This is a BUG and should be fixed ASAP. This isn't a feature, this isn't how it was intended to work it is a bug.
Please resolve this ASAP, it's concerning that an accounting package doesn't show all the transactions when you expect it to.
