Django Signals: The QuerySet value for an exact lookup must be limited to one result using slicing

i have this code in my models.py (post_save)

    class StudentsEnrolledSubject(models.Model):
        Students_Enrollment_Records = models.ForeignKey(StudentsEnrollmentRecord, related_name='+',
                                                        on_delete=models.CASCADE, null=True)
        Subject_Section_Teacher = models.ForeignKey(SubjectSectionTeacher, related_name='+', on_delete=models.CASCADE,
                                                    null=True,blank=True)

    @receiver(post_save, sender=StudentsEnrollmentRecord)
    def create(sender, instance, created, *args, **kwargs):
        teachers = SubjectSectionTeacher.objects.filter(Sections=instance.Section,Education_Levels=instance.Education_Levels,Courses=instance.Courses)
        for each in teachers:
            if created and teachers.exists():
                StudentsEnrolledSubject.objects.update_or_create(
                        pk=each.id,
                        Students_Enrollment_Records=instance,
                        Subject_Section_Teacher=teachers.all()

                    )

    class StudentsEnrollmentRecord(models.Model):
        Student_Users = models.ForeignKey(StudentProfile, related_name='students', on_delete=models.CASCADE, null=True)

    class SubjectSectionTeacher(models.Model):
        Education_Levels = models.ForeignKey(EducationLevel, related_name='+', on_delete=models.CASCADE, blank=True)
        Courses = models.ForeignKey(Course, related_name='+', on_delete=models.CASCADE, null=True, blank=True)
        Sections = models.ForeignKey(Section, related_name='+', on_delete=models.CASCADE, null=True)
        Subjects = models.ForeignKey(Subject, related_name='+', on_delete=models.CASCADE, null=True)
        Employee_Users = models.ForeignKey(EmployeeUser, related_name='+', on_delete=models.CASCADE, null=True)

when I used the **Subject_Section_Teacher=teachers.first()** i received no error but that is not what i want result, then i decide to change it to this **Subject_Section_Teacher=teachers.all()**
