I am having a similar problem. I was in Spanish I in Spring 2019 and now I am taking Spanish II in Summer 2019. The same textbook is used for both classes but when I tried to enroll in the Spanish II class, it wouldn't let me because it said I was already enrolled in a class at this time (talking about the Spanish I class from Spring). Does anyone know how I fix this?
Thank you for your post.
What is your intsructor's name, and the class section you need to be registered for?
I may be able to manually move you, but any grades you had in the previous semester section would be lost. This issue occurs when your previous instructor does not finish out their old section.
Have a great day!
