Spartan-6 LX150T development kit problem with schematic

This is in regards to an avnet aes-s6dev-lx150t-g. The schematics for this board show ( FPGA connections to the FMC connectors. FMC2 connector pin D8 and D9 pair are connected to 2 different FPGA pin pairs resulting in the two FPGA pins being shorted as follows.


FMC2 Pin Number             Net Name                                          FPGA Pin                    

D8                                         FMC2_LA01_CC_P                          V11, V12 (shorted)

D9                                         FMC2_La01_CC_N                         W12, V10 (shorted)


In addition its noted that the FMC connection uses 2 pins on the FPGA but, FMC pins C22 and C23 go to bank 1 whereas all the other FMC connectors go to bank 2. Is it possible that one of the shorted pin pairs should actually be used instead of this bank 1 conneciton.


Please confirm ASAP.
