Error Sed or Awk for lines between two strings multiple times and keep the last one

Hi,
I am trying to get lines between the last occurrences of two patterns. I have files that have several occurrences of “Standard” and “Visual”. I will like to get the lines between “Standard” and “Visual” but I only want to retain only the last one e.g.
Standard
Some words
Some words
Some words
Visual

Standard
Some words
Some words
Visual

Standard
Some words
Some words
Some words
Some words
Visual
Some words
Some words

I am trying to get the highlighted portion

Thank you so much
Dave

Code:
Standard
Some words
Some words
Some words
Visual
 
Standard
Some words
Some words
Visual
 
Standard
Some words
Some words
Some words
Some words
Visual
Some words
Some words
