Relevant generated routes:

    {
      path: "/account",
      component: _2479bbc0,
      name: "undefined___default",
      children: [{
        path: "child",
        component: _8329b026,
        name: "account-child___en-us___default"
      }, {
        path: "child",
        component: _8329b026,
        name: "account-child___en-us"
      }]
    }, {
      path: "/en-us/account",
      component: _2479bbc0,
      children: [{
        path: "child",
        component: _8329b026,
        name: "account-child___en-us___default"
      }, {
        path: "child",
        component: _8329b026,
        name: "account-child___en-us"
      }]
    }, {
      path: "/fr/account",
      component: _2479bbc0,
      children: [{
        path: "child",
        component: _8329b026,
        name: "account-child___fr"
      }]
    }

Problems:

• there are two children per locale route (should be just one)
• the undefined in /account route also looks wrong

[aldarund]

undefined goes from or maybe some other similar place, didnt digged fully https://github.com/nuxt-community/nuxt-i18n/blob/dc668952c4501c2e0b95603dd838b47ec18db0b9/src/plugins/routing.js#L28
e.g. name is not undefined and it appends prefix to it and hence the undefiend__default

[rchl]

Yes, looks like routes with children are not supposed to have name because one is not supposed to navigate to such routes directly.
