Android studio Giraffe debugger not working, no variables shown in the lower left of my screen

Question

I am using android studio Giraffe when i add breaks to the code in my app, and i run in debug mode, it doesn't show any of the variables in the lower left window such as i see in so many examples.

i have looked all over the internet and in youtube videos.

enter image description here

Any ideas why I can't see the variables when I'm in the debugging mode ??
