To change SUM field drag from "Choose fields to add to reports" into lower right box (Sigma Values).

To change days and hourse into english best would be to start your own Pivot table.

Just delete those sheets and go to your original data, select columns from A to K (last one) and Insert -> Pivot table

Then (back to picture above) insert Row labels nad Sigma Values again, and group data as you already learn.
