Printful action, Product Name dropdown doesn't match my store

I've attached a screenshot of where I hit a roadblock in connecting Payhip to Printful. I've tried several times (deleting workflows and starting over) but the dropdown for Product Name never shows my product(s). 

Out of curiosity, I went ahead and clicked "Save & Send Test Request" and in Printful received the order for a luggage tag (that I don't sell). Everything else on the order received looked correct. 

Thanks in advance for the help!
