You've got to be kidding me......that's such a simple explanation. It hadn't occurred to me that the wiring order at the BLTouch might have different standards. I hadn't found those charts you shared before, but that explains everything. While the BLTouch IS authentic from Antclabs, it is boxed in a Creality box and wired for Creality applications.
At least I understand the reason and how to avoid a repeat. Thank you!
