Max and Min temperature datafield problem - values are not actualised during activity

Hello, I am on 2.80 firmware. I added datascreen to Hiking activity. This datascreen has three fields, actual temperature, min temperature during last 24 hours and max temperature during last 24 hours. But these two datafields stayed blank only with dashes... Can check somebody this behavior on your Instinct please? Thank you. ciq.forums.garmin.com/.../1443422.jpg
