Total includes a configuration file that registers all the strings included in the Theme Customizer so you can easily translate them. This includes things such as your custom related posts heading, custom image logo, callout text, copyright text…etc.
Translating with WPML
The “String Translation module” is included with the “Multilingual CMS package” and will allow you to translate any strings not included inside posts, pages or taxonomies. It’s very easy to use and is located at WPML->String Translation.
Below is the link to the guide on the WPML website which goes into greater detail. I would strongly recommend you check it out.
