Actor snapping greyed out

Hey I’m using the mod tools for Squad. I’m trying to snap one object to another. I searched everywhere and all I have found is actor snapping, but this is greyed out in my options menu and I cant turn it on. Is there a way to turn it on or is there another way to align one objects transform and rotation to that of another.

Many thanks for your help

Seems you can switch it on/off with keyboard shortcut (ctrl+shift+k) but not in the preferences menu.
