Lazzah, all the videos are currently unlisted, so that is why you were unable to search for them. Three videos is better than just two, but this is really frustrating.
When I look at them in the Youtube Video Manager, they all have the same settings and the same number of published closed caption options, which should just be the one I made, as I unpublished the garbage automatic closed captions. R2T1 is from Australia, and I'm from the USA, so I guess I will need someone else from your region, the UK, to try out the CC option to see if this is a regional thing or not.
As another idea, I've edited the links below to force CC to be turned on by default. Once again, these work for me, but I'll need more people from the UK to try them.
