Resistor values on schematic are not consistent #2

As pcb/kicad4 is hand-copied version of pcb/kicad, it also contain the design issue described below.

lm6551

In this schematic, AD8138 x 2 (IC4, IC5) and LMH6551 x2 (IC2, IC3) are placed (for explanation purpose I suppose). Resistor values of IC2 are copy of IC4/5 but they should reflect values of IC3.

Investigating mhz100q_b subsheet made me confident IC3 values are correct. imp
