Hi,
Your tabs appear to be working, they are iterating through each tab’s content correctly.
There is however a lot of duplication for the “Add Content Element – or – Add Text Block” from within the backend, this could be due to the complexity of the layout.
I’ll get our lead developer to take a look for you also. It looks like you have a lot of modification to the WP editor, could you also temporarily disable all plugins apart from Swift Framework and test if you still get this issue?
