Remove end time from sidebar widget

I just updated to version 3.3. I am using it as a sidebar widget. Some of the events I include (such as meetings) I don’t want an end time listed because we do not know the length of the meeting. Prior to upgrading if I left the end time blank, it would only show the start time. Now if I leave the end time blank it will list the end time same as start time in sidebar widget.

Any way to remove end time.
Thanks!
