Pin labelling is very misleading #7

Pin ordering on JP2 in MKS TMC2209 V2.0_001 SCH.pdf is GND, VIO, OB2, OB1, OA1, OA2 pin ordering on JP2 on PCB MKS TMC2209 V2.0_001 TOP is GND, VDD, 1B, 1A, 2A, 2B

so OB2 is connected 1B, OB2 is connected to 1A, OA1 connected to 2A, OA2 connected to 2B....

does it need to be this confusing? Pretty hard to figure that was the problem with my setup, when I didn't realize OA2 is not 2A etc
