In the image you sent in attachment is hard to see the labels, but I assume there's a function called One email function. Probably it is splitting the object again in many outputs.

Try adding an AI Agent instead this custom function, it can summarize the emails for you, or just customize the output with a Output Parser.

Next time you attach an image, send it in good resolution and take it right after you run the workflow, se we can see the number of itens in the connectors.
