This component uses language strings to display expressions in the frontend. Depending on the language the correct language string to the corresponding expression gets inserted.
It might be useful to adapt these expressions accordingly. This can be done globally for the frontend by creating a language override.
How to create language overrides can be read here: Language Overrides in Joomla.
A list of the most important language constants and their default expressions can be found in the global options of the component.
