Slider issues - doesn't show Videos (Youtube, Vimeo)

In the example proposed for the Slider (see attach file), the video works for Vimeo.

When creating my post in Video format, including a category exclusively for use in the slider, and set up correctly, the video does not appear (see attach file). Note that the summary and buttons are displayed correctly.

How can I solve the problem?

Some evidences:
1. Error: Failed to execute 'postMessage' on 'DOMWindow': The target origin provided ('') does not match the recipient' window's origin"
2. Similar issue: "I want it to look like your example with a featured image in the background and then video starts up on the left of where the words are for the slide"
