Comment (by Sardorbek Imomaliev):

 Hi Carlton,

 Thanks for reply, it is not broken because there is no `Not Empty` choice
 in django itself
 created new issue https://code.djangoproject.com/ticket/30149

 > This looks like a (related but) separate issue. Can you submit a new
 ticket, something along the lines of "Empty value `selected` check in
 Admin Filter prevents subclassing" and we can have a look.
 >
 > At first glance I can't see how both `bool(self.lookup_val_isnull)` and
 `self.lookup_val_isnull == 'False'` evaluate as `True` in the `Not Empty`
 case. (???) Surely the existing `empty_choice` logic would already be
 broken if they did.
 >
 > If you have a PR (with a test case showing the broken example) available
 (or can provide one when opening the ticket) it makes it much easier to
 assess.

 > Thanks.
