Debug sticks are placed in the middle of invisible blocks in the "Operator Utilities" tab

The bug

In the optional "Operator Utilities" tab, the debug stick is placed in such a way that it appears in the middle of the list of invisible blocks in reading order.

How to reproduce

1. Enable and enter the "Operator Utilities" tab
2. Note where the debug stick is

Expected results

The invisible blocks (barrier, structure void and light variants) would be continuous.

Actual results

The debug stick appears after the barrier and structure void, but before the lights.

How to fix

The debug stick should be moved somwhere else inside of the tab so that lights immediately follow the barrier and structure void.
