Cyton BOM vs Schematic vs Design Spark Inconsistency

Hi,
I was looking through the schematics, BOM, and design spark (https://github.com/OpenBCI/V3_Hardware_Design_Files/tree/master/OpenBCI Cyton Designs) to find that there are 3 different components and wiring for the R11, R10, D10. This includes R11 resistance value (330k, 470k or 1k), R10 resistance value (10k, 1k, 220k) and the presence of D10 entirely.
Which document should I use as the final standard? And can I directly use the OBCI_V4_C_BOM.xlsx file along with the Gerber files (https://github.com/OpenBCI/V3_Hardware_Design_Files/tree/master/OpenBCI Cyton Designs/OBCI_Cyton_Plots) to fabricate the circuit board?

I have tried my best to search for relevant posts on the forum. Although some people mentioned similar issues, I have not found an accurate solution or explanation.

Many Thanks！！

    Hello @sunjc you don’t actually need those parts since they’re not relevant for this design. You don’t need the „ble enable“ part of the circuit since is not used at all. So don’t worry about that :)
