vBSEO error only visable in Google index

What is the date/time of the cached page? Is it indexed AFTER you made all changes above?

The catched page is from before but I fixed it right after making the screenshot above.
And the text have changed after that in the "google indexed page" Does it take time before google displays the indexed page from the time that it is cached?

Yes, it never has immediate effect and will be corrected once google bot revisit those pages and update google index.
