Will my offer get rescinded?

[Theron]

I have been accepted to Duke for the MS in ECE program for Fall 2021.
I just checked my proof of application and there has been an error. It lists my minor as "Economics" whereas I have no such minor.

I have not deliberately tried to falsify my education, I think it could've been a human error on my part (I wanted to specify minor as Electronics since it only mentioned Electrical Engineering as the major). I only saw this right now, and I didn't catch the mistake when I first submitted the application or I would've contacted the admissions team right then. I was able to view this from my "proof of application" which is for personal use only. 

 I have been accepted to a STEM MS and I don't see how not having an Economics minor should change anything.

Duke's my first choice, I don't know what to do.

Should I email said university about the error? I don't think I made the mistake. Will they rescind my application?

I cannot possibly imagine they would rescind your offer for this as economics is completely unrelated to your intended program. 

If you wanted to reach out about it, I would kindly say something like, "I wanted to just make sure my records are accurate with your program and I wanted to let you know that my undergraduate major was in "Electronics", as per my transcript. My application materials somehow reflect Economics. I'm sorry for any inconvenience."
