How do I see Interval stats?

When I do an interval session (running) and look at stats, it just shows as one run.  I want to know my stats (pace, time etc) for each leg.  Currently it just records the whole session as one run, so my pace is a lot slower than it would be if it had logged each interval separately.  I tried pressing the Lap button at the end of each interval but that just made it jump to the next rest or run interval. Is there a way to log each interval/rest individually?   cheers
