Ok thank you that answers half of my question but what about when it just won't match a single transaction. 

I currently have one that I'm having trouble with thats an expenses of $59 and I review and accept the transaction but then in the receipts tab the receipt I've uploaded won't match to the transaction and if I fill out the receipt info manually and add it, it adds another $59 to my books which then puts it all out of whack when it comes to reconciling etc. 

How do I match receipts to transactions/expenses when it wont automatically match them?
