I’m having a similar issue. For any events more than 24 hours out, it is only displaying the number of days away + end time.

I had to rebuild my MM after the Pi I was using crashed, so I believe I was running the previous version of MM before the rebuild. I seem to recall the calendar module displaying number of days in future + start time before. FWIW, I’m using google calendar.
