Contextual links doesn't appear

Drupal 8.2.3

Sorry for my English, at first.

I create a view.

Settings: Unformatted list, Fields.

And put fields:
Content: Link to edit Content [hidden]
Global: Contextual Links

But all of I get – its:
<div class="views-field views-field-contextual-links"><span class="field-content"></span></div>

Why Global: Contextual Links doesn’t work? =(

Thanks. =)
