Thank you Kevin. No, removing the expense from the report didn't work. However, when the expense was not in the report, it enabled an option called "Separate" the expenses (which I couldn't see anywhere when it was in a report) - so your suggestion was still very helpful, thank you!!

我选择了“独立”option and it was splitted into two: an expense with the correct amount and no receipt, and one with the Uber receipt and a wrong amount. I moved the correct one back to the report and reconciled as usual, and deleted the other one (bearing in mind the actual transaction of that Uber receipt has always been in the report all the time so not sure where that extra expense came from).
