Volvo Cummins Spark Plug Replacement

Spark plug change in a Cummins 12L CNG engine in a Volvo VNL. Very weird sentence that doesn't seem like it should go together but it does. After inspecting the plugs more, there is a gap between the electrode and strap but it's smaller than it should be. Couldn't really tell when I pulled them out.
