ST Training Log Issue

How do I change units so the charts and weekly, monthly… stats are in US units?
Also it seems that the goal feature is not working properly for me…
I set a goal to run 4 times a week and even tho my week shows I did just that, the goals show I am only at 3x, so I am behind.

Is there any tutorial about the features that are available?

you can change the units by editing your profile.
