Automator images to pdf: save location problem


I have an automator service which converts the selected images to a pdf.

It works but now I wanted to change the save path (right now its /desktop) to /desktop/docs.

I do this, save the automator file and it shows me the docs folder as path but if I run it, it saves the file to my desktop. If I close and reopen the automator file, the location went back to desktop.

Is this a know issue? What can I do to save the pdf to the folder?
