I would never consider Global Spread as important for a project. I find it just a convenience right at the very start of a layout where there are many parts. In fact, if I ever use it at all, it would only be the one time in a project.
The Global Spread is context sensitive. You need to be in "Default Canvas Mode" (View - Switch Canvas to Default F9) and you need to have the Footprint mode Icon selected
After all that, you should then see the Global Spread and Place option when you right-mouse-clink on the canvas.
Other than that, there is just the ol' fashioned way of just moving the parts around one at a time.
If you have further issues, there would be better qualified answers on the KiCad Forum
