linkable property overrides block usage

[CezaryH]

I can't use my own links and linkable property. That's template of my addon that uses crumbly, unfortunately when I set linkable=true, then in every li element there are 2 "a" elements

{{#bread-crumbs tagName="ul" linkable=true as |breadCrumbsComponent route|}}
  {{#bread-crumb route=route breadCrumbs=breadCrumbsComponent as |crumb route|}}
    {{#if route.linkable}}
      {{#link-to route.path class=linkClass activeClass="link"}}
        {{route.title}}
      {{/link-to}}
    {{else}}
        {{route.title}}
    {{/if}}
  {{/bread-crumb}}
{{/bread-crumbs}}

if I set linkable to false and remove if route.linkable statement then I'm not bale to say if element should be link or not (eg. last element in list)
