Troubleshooting Error Message: Creating a Cycle While Checking for Duplicate Contacts in Company and People Tables

I have a Company Table, and it does a look up to a People Table to see how many contacts I have for each company, there is a col that when I write true, will find contacts at that company, and I want it to write to a table Add People that enriches and then checks to see if that person is a duplicate/already in the People table - except it gives me an error message about creating a cycle and I cant figure out why
