where is the "retain state on slide revisit" checkbox?

Ahoy!

I am using Captivate 9 (version 9.0.0.233) under macOS (10.13.3 -- 17D102).

In the right-hand side-bar I can see the "state view" button and the "style name" section-header below that.  I believe that a check-box for "retain state on slide revisit" should come after the "state view" button and before the "style name" section header but I can't, for the life of me, see the "retain state on slide revisit" check-box.

Please compare "My_Computer.png" (first) to "Adobe_Documentation.png" (second) below.  Note that "retain state on slide revisit" is missing from the second image.

What am I doing wrong?
