Alright, I checked out the action and I see that you have it creating a text layer on the photo. The action that I use to watermark my photos uses a seperate image with the text on a transparent layer. I tried to make an image like this for you, but I don't have the correct font installed.
I recommend doing this:
Take a transparent image and run your test.atn on that. Merge the visible layers of this new image (keeping it transparent) and save it in a folder. Make a new action that takes this transparent image and pastes it over your photos. Hope this helps.
