It seems to me UWP is working fine.
At least on my end:

Unfortuantelly, it works on UWP only if you do not plan to add any other control to the page.

When I created a page with the calendar and nothing else, everything worked perfectly. I have enclosed the calendar in a StackLayout so that I would display a label under the calendar and the days were not shown any more on Windows (it still worked fine on Android). I have replaced the StackLayout with a Grid and the calendar worked again on Windows. Unfortunatelly, I continued by replacing the label with a more complex custom ContentView and the calendard again got broken and did not displayed any days on Windows.
