Why individually rendered form fields not posting in Django?

I have a class based UpdateView that works fine if I render the form as {{ form.as_p }}. It updating the values, but looks bad.

If I try to render the fields individually it does not updating the values.

I can’t figure out how to fix it, I’m not so familiar with class based views. I don’t think there is a validation error (i don’t know how to check it in class based views) because {{ form.as_p }} works well.
Thank you in advance if someone can help me out!

models.py

class LeaderFeedback(models.Model):

    def __str__(self):
        return str(self.employee)

    employee = models.ForeignKey(User, on_delete=models.CASCADE, null=True, blank=True, related_name="employed")
    leader = models.ForeignKey(User, on_delete=models.CASCADE, related_name="employer_leader")

    goals01 = models.CharField(max_length=100, null=True, blank=True)
    goals01_deadline = models.CharField(max_length=30, null=True, blank=True)
    goals01_value = models.IntegerField(null=True, blank=True)
    leader_comment = models.CharField(max_length=500, null=True, blank=True)
