remaining days no longer available after update to fw 10.0

Hello. Yesterday I updated my instinct solar to fw 10. After the reboot the battery widget is no longer showing the reamining days. Instead I constantly see a +infinite symbol even though the battery left is 10%.. Any suggestion? Moreover altitude calculation which seemed to be ok with version 9.94, now is once again completely wrong .....

Sad to see a good product so heavily affected by buggy software......
