Glad I could see the coding error on the first problem :D

You can delete the one you don't want leaving a redirect behind. I personally find redirects messy and end up just going and fixing up the pages missing the deleted info.

use this Special:WhatLinksHere page to see if it's only a few pages with the wrong template or a lot, if it's only a few then I'd just delete it and go edit those few pages without leaving a redirect.
