I am in charge of re-designing our projects template here for the company I'm working for. I've set dependencies and all tasks have a start after and duration, but when I test the template, something's not right.

In my first milestone with a tasklist assigned to it I have 4 tasks with a 1 day start after, and 1 day duration. I entered the project yesterday. My first task is showing start 6/1, due 6/1, but the remaining tasks are showing a start of 6/5 and due 6/5. 

I see similar instances throughout the project, the first one in the task list will have one day, while the rest will have another date, all within the same task grouping.
