Filtering with None

[ceoro9]

When you specify choices with None option on model field and in admin model set that field in filters, something really strange happens when you choose None option in pop up list, I mean everything works okay on backend, but here is the problem with styles.

# models.py
YES = "y"
NO = "n"
NOT_FOUND = None
YES_NO_CHOICES = (
    (YES, "yes"),
    (NO, "no"),
    (NOT_FOUND, "not completed"),
)

called_y_n = models.CharField(
        _("Called (Y/N)"),
        choices=YES_NO_CHOICES,
        max_length=10,
        null=True,
        blank=True,
        default=None,
        db_index=True,
    )

# admin.py
class Admin(admin.ModelAdmin):
    list_filter = ["called_y_n"]

---

When you choose not completed (None) option.
