Permalinks change and Sample-page stays sample-page

Hi,

I changed the Permalinks and there is a page that is called "sample-page" that stays sample-page even when I change the slug line - it works for a minute then changes back to sample-page. I have several children built on this page, so erasing it and making a new page would be a lot of work. Does someone know a way to change this tittle?

Thanks

 

OK, I got it to work. I had to change the slug-line, and update the page! I forgot to update. Thanks.
