Area of Study automatically changed from Mech. Engineering to Undecided on application. Questions

I applied to UNC Charlotte last December, and as the title states, I checked today and the Area of Study changed to Undeclared today. What does that mean? Could I be accepted but not to engineering? Could I be declined? Any knowledge would be greatly appreciated. Thank you.

Looks like it is a possibility that they could admit you to the school but not your major. If you do enter as an undeclared student, http://engr.uncc.edu/current-students/advising/freshman-advising-changeofmajor-information indicates that you would need to earn a 3.0 GPA with no grade lower than a C to enter the mechanical engineering major.

Do you have applications to other schools where you may be able to get direct admission to your major, or where entering your major is not difficult? (Other NC publics with mechanical engineering are NCSU and NC A&T.)
