Hi Simone,
Thanks for getting in touch!
I believe that text and those sharing options are coming from the theme or another plugin. Neither The Events Calendar nor Events Calendar PRO have social sharing options built in, so that leads me to believe they are coming from somewhere else.
I looked at your site and it appears Avada is the theme you are using. I looked at the source code and it looks like the theme has a social sharing option and that is where the text and icons are coming from. I was also able to find documentation on it here:
https://theme-fusion.com/avada-doc/options/social-icons/#SocialShareBoxPanel
I would suggest reaching out to the Theme Fusion support forum for more guidance on how to change the text for the sharing options since it appears they are coming from the theme.
Cheers!
Geoff
