The single select and checklist fields both have the mentioned field setting, however the behavior is different for solution Admins when checked: >checklist - when checked, Admins cannot edit or add items to the list until the box is unchecked >single select - when checked, Admins CAN edit and add items to the list, regardless of whether the box is checked For consistency and clarity, I recommend harmonizing the behavior of this editing permission. I'd suggest making the single select act in a similar way to the checklist, which would can help avoid accidental option entries by Admins if the desired list of options is already configured.
