Courses page not working for the Mathematics Uniformization course

[peucastro]

All international students (those with ingress regimen "Special Contest - International Student") are automatically enrolled in a mathematical uniformization course in the freshman year (more information about it here).

I have already completed this course, and my status correctly shows "Not Enrolled" on SIGARRA. However, the new courses page displays me as currently enrolled in this course.

I am also encountering the following issues:

• Error: "Unsupported operation: Infinity or NaN toInt" at the AverageBar.
• Error: "Null check operator used on a null value" at the LazyConsumer.

All the other courses pages are working fine for me, including Continuing Training Units (such as EBEC).
