Seeing trips shorter than minimal distance

We are using Traccar to track dogs and now we are trying to see a list of dog walks using trips. Problem is that we see trips with distance less than the value in 'report.trip.minimalTripDistance'

For example, with the default value of 500 meters, we still see trips shorter than that:

For internal calculations we use distance between reported GPS locations, but here you see distance based on odometer, which could be the reason for the discrepancy. I recommend checking the raw data to confirm this.
