Running Workouts - Pace set to miles not km

I’m trying to use the workouts for running. 

For the tempo run of 4 miles at 92% of 5km pace.

92% of my 5k pace is 6:28/ km. so 4 miles is roughly 42 mins.

On the workout it sets my pace to 6:28/ mile for 42 mins, which is 8.85km.

The same problem exists for both of the speed workouts as well.
