Why is the watermark automation not working?

I've got a maybe not that different issue with watermarking not functioning properly. Automation, done as described above, sort of works for me. The problem is that after watermarking, it leaves a copy of the non-watermarked file in the folder. Not only that, but there often a second (watermark) (watermark) file add. Adobe Lightroom makes it easy, but that's the only reason I've used it in the past.  I think the main problem here is that Dropbox doesn't want image-makers as customers anymore. We complain too much.
