Lap pace alert first lap always 0:00 since 10.78 / 11.10

For the first lap I always get a 0:00 lap-pace on the alert-screen - no change if it is an auto lap or i hit the lap button.

From lap 2 everything is ok, in GC the data for the first lap is also ok... (6x Sapphire). Anyone else with this problem?

For the 1km autolap it helps to use the lap time (it is the same, so no calculation neccessary), but if i manually hit the button after 2,583km i would like to have the pace instead of the time...

Before 10.78 everything was OK.
