Two File Upload forms not working

I have a form with two upload fields where users can attach two different files.
For some reason, they are being uploaded to the folder correctly but they only one file is being attached
​
Here's the debug code:
​

Array
(
    [16] => Array
        (
            [DB Save] => Array
                (
                    [Queries] => Array
                        (

                        )

                )

        )

        (
            [Files Upload] => Array

                        )

Do you have any configuration regarding attachments in the Email action ?

If your form is simple enough then just rebuild it in the new v7
