Excerpt Macro Include does not update content

Lets say I set a excerpt macro in a page-A. And an excerpt macro in another page-B. So far so good.

Now I decide that that excerpt was incorrect, so I delete the excerpt macro in page-A and create a new exerpt macro in that same page but with other content. I could also not delete the original exerpt macro but simply remove its contents and then move the excerpt macro to another area of my page A in order to put inside the excerpt macro another content. The result in both cases is the same:

-in page-B I don´t see the changes reflected!!!!

So I delete the excerpt macro and the exerpt include and save page A and B. Now I recreate everything again AND page-B is STILL showing the original excerpt macro I first place in page-A.

This is ridiculous. How come nobody ever checked that if you update the contents then the exerpt insert will also reflect those changes? The excerpt macro is basically working as a screen-shot. Or worse.
