App reports of 10K miles but shows less

Hello,

When I set a auto recorded trip to business, I get a message stating that I have gone over 10,000 miles and that I can only claim the lower amount for that this trip. However on the mileage tracker is shows that I've done less than 10,000 business miles (not even 800 yet). I've also downloaded the mileage from the website and that shows I've done less than 800 business miles.

I don't know why I'm getting this warning
