Gmail Watch Emails outputs 5 bundles but only 4 reach the Filter-possible bundle handling issue?

What are you trying to achieve?

when i change the mapping field from the Google drive module upload a file to something different then “Attachements[ ]:File name” from Watch Emails module all 5 bundles arrive at the Filter.

My goal is to automatically process all Emails which Contain a particular Phrase in it and contain a pdf attachement, when executing right bundle 4 and 5 should pass the filter — each containing a PDF attachment — and upload the attachments to Google Drive.

Each email also contains an embedded logo image at the end of the email body. The Gmail “Watch Emails” module detects both the PDF and the logo image as attachments.
