Clarification on the use of an external resistor if gain=1

Question

Hi, trying to simulate LT6370 on ltspice I am noticing that using a 0 ohm resistor (RG) the output is different than not using it (thus leaving the two PINs unconnected). 
 Is this a simulator error or is it safe not to connect the +-RG PINs in case the op-amp is used with GAIN=1? 
 
 Thanks!

Hi m4tr1x , 
 Good day. I agree with Achim. To simulate LT6370's gain=1 behavior, you should leave the RG pins open.

With this, the model seems to work correctly in terms of gain setting. Thanks.
