Issue with reading receipts

Was going thru the L4 notebook ‘Creating use cases for imagesd’, but when I run the Receipts example, the answer says the breakfast and lunch total exceeds the daily allowance of USD 40 on 31-Aug. But these two are on different dates, and neither does the total exceeds the limit. Why is this error coming. I am using exact same code as in the notebook, just using my own Google Cloud credentials. ? Pls advise.
