Issues viewing stack titles

Hi,
Im a rapidweaver user for 10 years and have used it to create my own sites and not as a commercial web developer.

Rapidweaver Version 8.5.1 (20823)
Stacks Version 3
OSX 10.13

My current and most challenging issue is the view. For some reason I have lost the tabs As I call them which indicate the Stack you are in or the substack which is there on the page.
This recently stopped showing and I have used all my sites and Demo sites I have from the past to see if it is something with the current project.
But it is now not visible on any project.

Best description is the 2 images attached. The one with the Blue circled highlights is what I am referring to and the other image is showing without where the Red circled highlights are where its all gone missing.

I have reviewed many topics and used the inline help to no avail.

Something is wrong and I could have accidentally keyed some keystrokes to have made it disappear ?

Kindly put me out of my Misery as it’s hard to edit the project without these.

Thanks

Hanif

You want the 3rd option in View Mode.

Highlighted in yellow.

Thank you.
I can’t believe I didn’t notice this change.
Normally I never touch this view.
What a muppet I’ve been.
