Hi Inga!
Thanks for reaching out to us! I’d be happy to help you with this topic.
Having a link to register for an event in the list view is not a built-in functionality of The Events Calendar. However, if you are looking for an event registration functionality, then I’d recommend you check out our Event Tickets Plugin, which also adds a Buy Now button to the events listings > https://theeventscalendar.com/introducing-buy-now-buttons/
As for the screenshot you sent, I’m not really sure I understand where that link is coming from. Is that from your current site? That might be something coming from your theme or another plugin/customization. Could you please share a link with us so I can have a look at it?
When coming back, please share with us your system information by following this guide > https://theeventscalendar.com/knowledgebase/sharing-sys-info/.
Let us know about that.
Thanks,
Victor
