Special:Badtitle/NS90:User talk:Caig/Getting my head around re-directs

I can't get my head around this one. I started from here and asked "What links here?" This gives me 5 pages, of which the first is Italian: see Special:WhatLinksHere/Peripherals_Problems. The problem is that I can't work out where this actually is - going by the link I would have expected it to be a part of Troubleshooting/it - is it? Rather than just breaking links, I intended to simply replace the Peripherals Problems link with Troubleshooting/Peripherals Problems, which would have let me get rid of the re-direct. Am I misunderstanding this? I don't want to mess up anyone's work :-)
