mysql update parent updates all column values in child - mysql

Question

I have the following tables:
-users(not important here)
-students
-courses
-enrollments
the students and courses table have a "active column"
the enrollments table have a "course_active" and "student_active" column.
I am trying to set my DB in such a way that when I change active for student or course this will cascade to enrollments.
Unfortunately I am seeing that when I update an active value on "students/courses"
the whole column of "student active" or "course active" changes.
I would truly appreciate your input and assistance on this matter.
