When supplying your artwork, it's generally a good idea to delete the template layer before saving and submitting your file. The template layer is typically used as a guide to help you position the various elements of your design, but it's not intended to be included in the final version of your artwork.
To delete the template layer, simply open your artwork file in your design software and locate the template layer in the layers panel. Then, select the layer and delete it, making sure to save your file afterwards.
