2nd kilometer split time not shown

Example: a run with first km done in 4:20, second one in 4:25, third in 4:10, fourth in 4:00

At second km autolap shows only the total time (8:45) with 0:00 for the time of second kilometer. Since third km, it correctly shows 4:10 and 12:55, at fourth km 4:00 and 16:55 and so on

This happened also before upgrading to 19.20 and only at second km
