Title related products single products page

Hi,

I was wondering if you could tell me where to find the file to translate the related products title on the single products page. The one above the slider with 4 related products. As you can see in the attached screenshot it says ‘Andere suggesties’ but I can’t find the file to change this. I tried theme files, Woocommerce files and string translations using WPML.

Really hope you can help me out.

Regards,

Johan
