Code worked under the free version, but not paid version

I utilized the free version of the plugin and my code worked where I’m pulling JSON data into each slide.

However, because I didn’t like the watermark, I decided to pay $15 for the pro version.

After paying for the pro version, my third slide where I’m pulling in data now does not work. I’m pretty sure nothing changed but am troubleshooting it currently.

Any thoughts as to why this might not be working now?
