I have created an automation that triggers on list entry. 

However, despite contacts being entered into the list successfully, and the appropriate topics associated, the contacts are not being put into the workflow. They are being enrolled into this list through a Zapier automation. 

As you can see, the contacts are being enrolled into the list successfully. 

But the contacts are not entering this flow at all. 

I can't see a reason why the automation is not successfully running. 

Any help is appreciated.
