I have some instances where I changed the name of a page and now both the new URL and the old URL are showing in the code. How do I get rid of the old code that is causing a 404 error? See the screenshot. The broken link is /blog/e-coaching-choose-career
(Additional info: Support said the old code would disappear eventually, and that I don't need to worry because Google can't see it, but I just looked on Google Search Console and Google DOES see it as broken.)
