Describe the bug

A clear and concise description of what the bug is.

Strangely, the month switches with the day when loading the qif statement. The source qif data shows the dates as dd/mm/yyyy however part way through, the dates are switched to mm/dd/yyyy. See screenshot.

In this case, when dd >= 12, mm is swapped with dd
