Tides and Currents

I am new to using tides and currents in Coastal Explorer.
I have downloaded the necessary file.
I have scheduled my route for a time in the future but the tide and current information on the route is for the current day not the day in the future.
I can click on the tide or current icons on the chart but I then have to change the day to my departure date. When I go back to my route the current information is still for the current day.
How do I get the current information on my route to be the same as the day I am scheduled to leave.
