I have had a problem since the update with mileages not showing correctly and therefore MPG being calculated wrong, I've checked what I've entered and I'm correct but the system has worked it out wrong.
As you can see April 5th's Odometer reading falls between that entered on April 11th and April 19th. Either the dates or the odometer were swapped. Please correct and that should resolve your discrepancies.
As for fuel-up #22 (Feb 14th) I'm not sure what the problem with that one is. Can you explain the issue?
