Troubleshooting Conditional Workflow for Content Enrichment

I'm running a self made waterfall of recent content, so checking if they posted on Linkedin, if not run an enrichment for if they've posted a blog, and so on and so on. I made one final merge column for the final results of whatever was found. When adjusting the conditional run settings, I used "Only run if Final Results Column" is not empty. Then it gave me an error, didn't save my changes, and says this workflow would cause an infinite loop and make the workflow not work. What does this mean - does this mean I should instead set up my conditional waterfall one at a time, in between each step? So run Column B if Column A came back with nothing, and so on and so on
