Translating with Polylang WordPress plugin for Sparkling theme


I am giving this great theme a try and so far everything looks great, but for some reason I am not able to switch the language of the “Sparkling Popular Post widget” title. I am using Polylang plugin and the language used as widget in the theme is showing up as strings under Polylang plugin. I am able to switch and change the copyright string language but not the “Sparkling Popular Post widget” title.


Unfortunately, I am not familiar with Polylang plugin and I only use WPML to create multilingual websites based on WordPress and Colorlib themes.
