Wall Wrapping not Working

Maybe I’m doing something incorrectly.
This video shows a selected wall 1) not responding to wrapping settings.
(Toward the end it also shows 2) the wall responding to a single click as though it’s a double click and launching a style editor for the wall -which 3) never seems to be a window from which I can edit the wall style, by the way – but 1) is the main problem here.)
