PDF Attachment: Why am I receiving two PDFs when only one is selected?

2- I've activated the "PDF Attachment" option but now I receive in my notifications 2 forms (one with the data information, the other one without) even if only one is listed in my parameters

If I understood correctly, you are receiving two PDF Attachments via Email Notification, but you have only one PDF Document. 

To which form is your issue related to? Please provide us a form URL.

I suspect that you also created a Fillable PDF Form and that the PDF Form is attached along with the PDF Document. If this is the case, please delete your Email Notification and create a new one to see if that will resolve the issue.
