Issue with re-ordering tabs

Hi,

Not 100% sure if this is a theme issue but could really do with a little help.

I’m trying to customise the tabs on a Woocommerce store running the Generatepress theme and can’t seem to get the tabs re-ordered.
As part of the customisation, I’ve done the following:

Renamed and changed the heading on the additional information tab to “Dimensions” – this worked fine.

Added a new tab based on a custom field called “Features” – this worked fine.

I’ve then tried to re-order the tabs using the code from the Woo site so instead of the original order of:

Description > Dimensions > Features

it should be

Description > Features > Dimensions

However, all that is happening is that they stay in the same order and a gap appears inbetween the first and second tabs.

Any help would be appreciated 🙂

The full script of the functions.php file for the child theme in use is as follows:

/**
 * GeneratePress Child Theme functions and definitions
 *
 * All functions are prefixed with gpc_
 *
 * @package GenerateChild
 */
