Try this:
Make sure that you are using the Face option for placing the component.
Turn off the Original Path by selecting the Divided Path and using:
Start the place Component command.
Make sure that you pick a Node on the Divided Path to place the Component.
The Repeat button should now be visible.
Note: you can set a Node of the Divided Path as a workplane (the Placement Plane dropdown in the Options bar will read “Divided Path”), but placing a Component on such a workplane will likely mean that the Repeat button will be grayed out.
