Ski Lap Count

Today I tried to use my Epix to track a ski activity. I cannot ski and I'm learning on a very short and easy track (around 150 meters) with a lift on one side. Epix tracked only the last lap of the activity: basically, every time the ski lift brought me again on the top of the track, lap count reset to 0 and all statistics (and gps track) related to the previous lap disappeared. If I turn off autolap and I manually use the lap button, the session is recorded in the right way but it's a pain because I need to stop the activity to avoid recording the lifting.

It seems an intentional behaviour but I cannot explain the reason for that. Any idea?
