WEBENCH® Tools: filter design tool questions

Tool/software: WEBENCH® Design Tools

hi

filter design tool has been updated ，before it was updated,i use it to design a bandpass filter Gain 1V/V ,center frequence 20k Hz,bandwith 10kHz,2 order. it just like this picture: 

after it was updated,i use it to design same bandpass filter,but  it is different from the old circuit,there are two resisters which are different,i have use red pen to tag the different resisters in the first pictures，and the second picture is the new design.

why there are differences?And I use multism to simulate，the first circuit gain is 1V/V,but the second circuit is 2V/V.

which is rignt?is the tool wrong?

Thanks sincerely.
