Tab Element not working on homepage

Not sure if it's because of the recent Upfront update but the tabs element won't switch tabs on the homepage ( They will switch in the upfront editor but not on the live site.

Screenshot 1 shows the tabs element on the live site when I can switch tabs.

Screenshot 2 shows the Upfront editor where I can switch tabs.

Screenshot 3 shows a tabs element on a different page (in this case: being functional.

Screenshot 4 shows a tabs element on the homepage of the main site of the Multisite being funcitonal. (this is for reference)

I'm also having another problem with sliders on the homepage that I discuss in the thread here:
I'm assuming these two issues may be related.

Hope you can help!

Much Love
