Translate titles

Hi plugin Author,
I have added your plugin, but don’t know how to use, as before plugin I can translate the products too, and now I have some titles which can’t translate, for example Related Products or Category title – how can I translate through your plugin
example can see in this page https://dvconsult.digitalpome.com/hy/product/pvqits-artadranq/
Any advice will be great.
Thanks
