Wagtail Localize多语言URL异常：第二语言路径被追加默认语言前缀致404

访问http://127.0.0.1:8000可正常跳转至英文首页http://127.0.0.1:8000/en/，符合预期；但尝试访问中文路径http://127.0.0.1:8000/cn/时，英文locale前缀「en」会被自动追加至路径前，形成http://127.0.0.1:8000/en/cn/或http://127.0.0.1:8000/en/cn/about/这类错误路径。
即使手动修正为预期的http://127.0.0.1:8000/cn/about/，「en」仍会被自动追加，导致页面返回404错误，点击后台的「实时预览（live view）」也会出现同样问题。

错误信息 #

页面未找到 (404)
请求方法: GET
请求URL:    http://127.0.0.1:8000/en/cn/
触发位置:  wagtail.views.serve
使用website.urls中定义的URLconf，Django按以下顺序尝试了这些URL模式：

en/ django-admin/
en/ admin/
en/ documents/
en/ search/ [name='search']
en/ _util/authenticate_with_password/<int:page_view_restriction_id>/<int:page_id>/ [name='wagtailcore_authenticate_with_password']
en/ _util/login/ [name='wagtailcore_login']
en/ ^((?:[\w-]+/)*)$ [name='wagtail_serve']
当前路径 en/cn/ 匹配了最后一个模式。
