multi-day events

I feel sure that a multi-day event used to show 'from' and 'to' date but now it just shows 'from' date, but maybe it is a change to the information provider.

It only affects events that are multi-day 'All Day' events.

I only want one entry showing the start and end date - same as a single day one showing start and end times, not the multi-day option which gives me an entry per day.
Any chance you could adjust ?
