Making a Postcard in Photoshop need to turn off template layer?

The  Tiff file was downloaded from Modern Postcard  and it shows the guide lines in making a 4x6 size postcard. It shows different colors on my screen. I did get a email from Modern Postcard saying files looks good but I need to turn of the template layer in their file before they save the pdfs. I've looked on the histoy layers and do not see any template file.????
