Hello @MihaiHN ,
The theme does not have the option to change those names. It requires code customization and as much as we would love to help you with this, we are unable to do as it falls beyond the support we offer for our product.
For this, our suggestion to hire a professional developer so that your theme is not affected in any way.
To hire a developer, follow below-given link:
