Open Water Swimming w/ Garmin Swim 2: in Training summary no map with track shown

Hi,

I'm wondering why I'm not able to the map with the track of my open water swim. 
The distance seems to be calculated properly i.e. GPS works.

Garmin Connect: 5.3.0.41 (ios)
Swim 2 Software Version 3.10

I would appreciate if anybody could help me.

Best regards
Michael
