Buttons are linked to wrong URLs

Hi! I’m having this weird problem.

I’m using SiteOrigin carrousel to insert various SiteOrigin Hero widgets. Why? This is the page of a band, I need to have one slider at the homepage with upcoming show dates. Every show has a different background and a different link to buy tickets.

The problem is that the buttons work at random. Sometimes the button of the first slide links to the correct site, then the carrousel shows the next date and the button changes but it links to the same page, once it goes back to the first date now both slides link to the second date tickets. And if you use manual controls, it works the same.
