Text Widget | Parse as a Post: Not Functioning as Expected

[rod]

So I have an odd little issue. I am trying to use a plugin "shortcode" (or whatever the proper terminology is) in a Text widget but it is not working.

Specifically I am trying to add [carousel{"items":1,"lazyLoad":false}] to a text widget. I do have the Parse as a Post? (Take all post-related plugins into effect) selected yet when I view the page that has the widget on it the Carousel plugin does not seem to be kicking in and doing what it should.

Is there something I can add to make sure the "parse as a post" is doing what it should be doing?

Thank you.
