MPG calculation wrong (drop to 4.7)

Mine is a gas version 2018 Turing L. Purchased 3/24.

1st pic was taken yesterday, tank almost empty. MPG=17.5 which was normal.
2nd pic is after I fill 17.691 gal until full and made several trips. MPG = 4.7 which is obviously wrong.

Maybe I got too few gas left before I refill which causes very low fuel level sensor value. I guess a program overflow/underflow happened somewhere. :(
I clear Trip B every time I fill tank to full. But right before I'm doing that today, I found this problem. Luckily I got a pic yesterday to compare.

Only Trip B is shown here, but total MPG and Trip A MPG all went wrong to 4.7
Mileage data all seems correct, so I suspect it's about fuel level.
