Easel choice to Lock/unlock motors not appearing

I find the option to lock and unlock the motors on the cut dialog boxes really useful. But the are no longer appearing. Attached is a screenshot of what I am seeing and what I used to see. How to get the buttons back please?

Hi Chad,

I think you might need to add a second bit to the project in order for those buttons to show up.

Well done! Makes sense (kind of) that it works that way. If you left the choice on, it would convenient to let us decide who to lock. For instance, I prefer locked so I could do something like powering up the router after setting the home. Thanks!
