Clarification: 02_Motor_Front_Spacer compatibility with DM-J4310 and DM-J4340P dowel-pin patterns #26

I have a question about the motor spacer used in hardware/reBot_B601_DM.

In the v1.1 assembly, 02_Motor_Front_Spacer.step appears to be used as the front spacer for Motor 2–5. The BOM also lists both DM-J4310 and DM-J4340P motors in the same robot.

However, when I checked the motor interfaces, the dowel-pin pitch circle seems to be different between the DM-J4310 and DM-J4340P: approximately 24.3 mm for the DM-J4310 and 24.0 mm for the DM-J4340P.
At the same time, the same 02_Motor_Front_Spacer.step seems to be used across multiple joints.

Could you clarify the intended design?
