Default language tab shown twice in django admin

[GitRon]

Hi guys,

I'm using your package (v0.12.1) and it works great except one "styling" glitch.

In the django admin (django 1.11.5) the default language tab is rendered twice when selecting the default language (in my case "de"):

The same with the select on top of the page. The second select just contains "de" and is redundant.

Any ideas what I might be doing wrong? Or is this maybe a bug?

Thx in advance! Ron
