Shortcode Error

Trying to make it so that the word that is shown is completely random instead of going in order.

I used the following shortcode:
[randomize random='1']

However, when I do that, it only displays the first entry on the list. Even after refreshing, clearing cache, using a different browser, it’s still only showing 1 entry and it’s the first one on the list.

Side note: I am using Elementor, and I’ve tried using the Shortcode widget as well as the HTML widget. Both should work fine, but I get the same issue with both.
