Hard to read because of the glare. Is the first picture showing 60.2 miles driven and you filled up with 3.274 gallons? And the second picture shows 50.0 miles for 2.345 gallons consumed?
The programming on your Acewell is way off; it's not the K-bike. At that rate of consumption, liquid gas would need to be pouring out the exhaust.
Check the tire circumference value and make sure that it is reasonably close to the actual circumference of the driven wheel. It is critical to get that number right if you want the odometer to register distances correctly and accurately. Are you using the rear OEM sensor or the Acewell magnetic sensor? Drive a known distance after resetting one of the trip meters and make sure the odometer is reflecting that distance exactly. That will either validate the Acewell's programming or indicate the area where your problem lies.
