@joseph-benguira, ok thanks. That's good. One of my pages was taking a while to be crawled after changes and google would let me submit for re-indexing, but it's all fine now. Thanks for your help!
@joseph-benguira, thanks for your help. I can't tell what would be doing it. I originally made this a couple of years ago when I think the functionality for blog pages was a little different. I think originally the slug couldn't be changed. I use the re-directions that the all the variations of URL's open the page, but I'd rather have more control over it.
