I am working on a project I got from someone else. While setting up my sheet I ran into something that had me confused. I figured out the problem and hoped this would help anyone else who has a similar issue.
Main floor and upper floor: true north and project north looked and functioned correctly. Basement floor: true north and project north showed exactly the same although, they should have had 2 degs difference.
Solved: basement floor plan was rotated 2 degrees. By selecting the floor plan crop region and rotating it two degrees I was able to fix the problem. Now project north and true north show properly on all floor plans.
Tip: don't rotate items on the sheet unless you absolutely have to.
