I matched all the dates and times and deleted all the tasks... it worked.
But the "Project information" Title, that shows up at the top of the Gantt chart
still shows the "finish" date/time as 24.5 hours till finished..

But once I enter a start task and time, the Project info title reflects the latest "finish" time...
It works as it should and looks correct, but the set up is not correct, and that kinda bothers me..
