When using as a nav in the car distances are incomplete

When I drive with this app as a nav in the car, the distances to the next exit are in kilometre whole numbers only, except the last kilometre where they are in metres. Example: If you are 3km from an exit, the distance to the exit stays at 3km until suddenly it’s a 2km and then suddenly 1km. There are no decimal points on distances. This is something all other navs do.
