In the Single Value Display, every field updates properly except for Energy. When I am showing Current, for instance, and I change to Energy, the last current value still remains on the display. Changing statistics for the Energy field does not make it start updating.
I confirm this issue is present in 0.4.6. The problem is fixed in commit 7ebdebd4, and it will be fixed in the next Joulescope UI release, 0.5.0.
