All day event is posting twice to the calendar

Hi Andy,

When adding a new event to the calendar and marking it as an ‘All day’ event, it adds it to the ‘calendar listing’ twice;

1. As an All Day event
2. As an event from 12:00 am – 11:59 pm

See here for example: https://rich.bento.me.uk/events/ if you click on 4 weekly list.

I’m using the shortcode: <-- (brackets replaced of course) It also doesn’t quite display correctly on the ‘click on day’ if the ‘Event description field is empty. An example of this can be seen on the calendar if you click on Saturday 20th April 2019 – Jo’s day off. Hope you can help, Many thanks,
Rich.
