Is TESU's academic evaluation less accurate for out-of-major calculations?

[Pelican]

I declared a major in "History" when I applied for TESU. When I use the "Academic Evaluation" option in Online Student Services, some other degrees can be calculated, but I notice it sometimes uses credit earned prior to my first BA in the calculations within my the degree area (e.g. I took design classes under my first BA and they are showing up in a major in Technical Studies). Can some of the credits from the first BA be used to fulfill within-the-area-of-study requirements? Is the calculator less accurate when I use this "Academic Evaluation" feature on degrees outside of the majors I've officially declared as my major?
