INA1620EVM: Using external resistors to set the amplifier gain in INA1620EVM User's Guide(SBOU205-March 2018)

Part Number:INA1620EVM

1. R15=R20 is Not matched...

2. If we connect the IN- to GND，and Set R1=R7=1K ohm，R2=R6=2Kohm：

when using Equation (4), ,VRightChannelOutput = (1k/(2k+1k))*(1+2k/1k) * IN+ = 1* IN+

But using Equation (6) ,VRightChannelOutput = (R2/R1) * IN+ =2 * IN+

So is there something wrong....
