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
Regards
