Hi,
I've noticed that when I have task dates that are on Saturdays and Sundays, the Duration column in the project becomes inconsistent. I have a screenshot below

We can see that in row 2 for the Project Management task, there is a duration of 190 days. But row 3 below it for the Project Manager task says a duration of 192 days. Clearly there's some kind of wonky calendar thing going on here whenever there's weekend days involved (it's consistent when the start and end dates are weekdays), but I don't know where calendar settings are stored. Where can I look for the configuration/setting that is causing this weirdness, and how do I apply consistent calendar settings across the entire project?
