Measure works, seeing data not

Ive been using it for a few months and it has helped me to play more often with the tension range I like, therefore help me improve my game.
I couple issues are bugging me though:
1- in History the Curve view never works
2- in History it displays the tension in kg only
3- it should have a way to log how many hours were played since last measure
