Nested looper shows content in preview, but not live

Using ACF & CPTs, I’ve created “Destinations” & “Airlines”.

On Destination pages, the airlines that fly there are displayed in a loop.

I have another loop on a Direct Flight page, where I have all of the Destinations looping on the page.

Here’s the problem that I’m experiencing…

Each of the Destinations on the Direct Flight page is setup using a Flip Card. The Destination’s featured image is on the front and a shortcode of the associated Airlines is on the back.

In the builder, I’m seeing the first card display as expected… but ONLY the first card. It’s not showing on the second, third, etc etc.

On the front end, the back of the card (Airline Shortcode) isn’t showing at all.

I read on another post about this potentially being a known issue that’s being worked on. I am unsure if this is that, so I thought I’d try and post here. It’s about the only thing preventing me from launching this site, so it’s kind of driving me nuts.

Any suggestions?

Hi

  1. What kind of a “loop” is it? Custom or some looper provided by the themeco theme/cornerstone?
  2. What data do you feed into the “flip card” (what ever solution it is)? Or how do you fetch the content of the CPTs?

Which of the heuristics is correct: An airline has many destinations or a destination has many airlines?
