The Chinese label was replaced/fixed with English and is published in the Beta version v02.08.00.50 (latest as of this posting).
(FIX: 修复重叠区域稳定归属英文翻译缺失 · bambulab/BambuStudio@4a9a200 · GitHub).
The English label should read “Order-independent overlap carving” and description is:
When enabled, overlapping model parts are carved by bounding-box size so smaller embedded parts are not removed by larger parts due to volume order."
This option only shows up when “develop mode” is enabled. It is new as of v02.07.01.57.
