Windows 8.1 64-bit
Excel 2013 32-bit

I am now experiencing a small problem with the pop-up calendar.

When I open it, it does not go to the current date/month and, for some reason, it has a specific date greyed out (I am assuming this is because that is the date I created the calendar)

Photo attached.
