How to delete or rename Song templates

I created a new template for Songs, titled it "Reasonable Top Third", and somehow I now have 2 templates saved with that same title. I can't seem to delete one or rename one of them... Can anyone tell me a workaround? You surely can delete templates if you're allowed to create your own??

Seriously, as soon as I typed that out I saw the delete button. I have been working around that for 7 weeks - some days the brain just engages.
