I’m having a problem with some elements on the builder

Recently I’m having a few problems on the website. For example on the home page when you click on the button “Find Eircode” it should open a modal but now it’s not working and also on the page https://heaventree4.com/home-broadband/fibre/ a few tabs on the accordion is not working. It looks like to be some script conflict but I’m not completely sure. Could you help me with these issues?

Thank you
