Telegram giving me to messages

Hi.
I have this flow, that control a folder in my mail, and if there is a mail it grab the image and send it by telegram, and then delete the message.
My problem is, that I get two telegram messages, with the same image of all mails in the folder.

So every mail, is send by telegram two times before going to the next mail.
How can I edit the flow, so I only will get one telegram message, when getting a mail?

Add a debug node (set to display the complete msg object) to the output of your split node and run your floe.

What do you see? Then ask yourself 'Why do I see this?"
