Post title changed, permalink did not. How to fix?

Would love any help, I have my perma-link structure set to display the title of the page/post.

On this page: http://corporatebellyflop.com/buzzword-bingo-meetings-are-now-manageable

I changed the title from “buzzword bingo – meetings are now manageable” TO “Buzzword Bingo Cards”

You can see this reflected on the actual page post title (yes this is also mis-aligned, that’s another problem I’m having), but the permanent link in the code is still showing the original.

How does one get this to update when a post title is changed? (Or can I fix manually and just be very careful to make sure my titles are correct next time?)

Thank you!
