Font issue after Theme Update

Hello everyone and Happy New Year.

I recently updated the theme’s newest version (Souffle) and after doing that, the font of the Greek version which is translated (i’m using WPML plugin) has another font. The font “Roboto” doesn’t work properly when the language selection is Greek.

Here you can see the obvious difference of the fonts:
