That is an default woocommerce functionality. So it is hard to change the order or title name.
To do that, we have to change woocommerce php files.
And you can change the tab contents as you need. For the description tab content, please edit product page with elementor page builder.
Then, you can change the content with the elementor.
If you have any problem, please let us know without hesitation.
