Data for Interval Training is showing splits per 1km rather than each stage of the interval


I want to see my average pace during each stage of an interval training session however at the moment the data seems to be getting divided into both kms and the interval splits which is making the output relatively meaningless. For example last night I did a warm-up, then 4x6min threshold w/2 min rests, then a cool down; what i want is to see my average pace during each working period however my laps are broken up in whole kms and then whatever was left in each period; easier to show you...

I am using uploaded workouts so my watch does know that I'm interval training.

Please help?
