Click to reveal takes you straight to affiliate site and not the popup

I have been trying to figure this out for a while now.
Clicking on “Click to reveal” simply takes you straight to the affiliate site and doesn’t show the popup on site first.
If you click the title of the discount item then this works as it should and shows you a popup first, however everyone will want to click to reveal.
I am using the child theme “Coupon Theme S2” and previewing it works as it should but once downloaded and activated it doesnt and does what is discussed above.

Any help will be massively appreciated.

Cheers
