Intermittent error navigating to empty date range

[Hamilton Colyer-Long]

Scrolling back/forward through the weeks or months had an intermitted problem where it would load a blank data range and not show any data, but if you scrolled again then the date range went back to what you would expect and the data loaded.

I haven't seen this problem occur during pretty extensive testing over the last 2 days, it may have been resolved.
