Pro Features on Staging vs Live Site

We are currently using a staging site to make all changes and updates and push them to the live site when they are tested. Our Elementor Pro and Ele Custom Pro license is active on the staging site. The live site is never modified directly – it is always updated through staging. Elementor Pro features work fine on the live site but the Ele Custom Pro features do not work. For example, the staging development environment uses a slider for the custom episodes but the live site does not reflect this change. How can I get this plugin to support the staging/live workflow?

This is the staging (where the pro features work): https://dev-great-battlefield.pantheonsite.io/
