Ok. It was a refresh the page and clear the cashe thing

Only after I e-mail the blog help desk and read their "This has happened to a zillion people before you" answer and follow their instructions and refresh the page does the proper page load showing the changes I've made a million times.

Why this should be the case, I don't know. Every other blog I check is updated each time I go to it. Why mine needs to be "refreshed" this time (but never before) is a question only the sages of the internet can answer.

At least it's working now.
