Insert Gallery into Parallax section

I’m trying to enter a gallery into a Parallax section to avoid viewers leaving the front page. Is there a way to do this? I created a gallery on a page and then inserted the shortcode, this just displays the shortcode. When I insert a text widget, the gallery appears. What am I missing?

Hey there,
I hope you’re doing well today

The home page is designed with custom sections only in the home page.
In order to do implement you’ll have to use custom coding to achieve this.

In tis case it would be best to submit a feature request to our GitHub forum stating exactly what it is you’d like to achieve so it can be considered as a possible feature request.

Also to confirm, an issue with the theme, please activate a default WordPress theme such as twenty sixteen, and test to see if what happens.

Best Regards,
