Go to Kulg web page, log in. Click Overview menu, review data on "Running overview" Board. When Week Distance (km) is 0.00 km - all the metrics should be empty.

Bug: Intensity, High intensity and Elevation gain show "-%" value BUT HR vs speed shows "-100%"

Expected result: All 4 metrics show "-%" value.
