Some Posts Show Code Instead of Title

We have articles that are auto-created using data from an API, and published to WP and posted to Twitter. But while some of them are posting correctly, some others use the data point labels instead of the actual data. I’m not sure if it’s being caused by the plugin but is there any condition I could set to not post without the data filled in?

Any help would be much appreciated, thanks!
