Circuit schematic produced by Filter Wizard

I have just used Analog "Filter Wizard Beta" to design an OP-AMP 7-pole Chebychev low pass filter. My passband gain requirement was 15dB, ripple 0.1dB The magnitude plot and data file meet this specification; however I am not sure if the proposed circuit schematic does. Only the first stage has greater than unity gain. But, unless I am mistaken, the two10K resistors shown will give a first stage gain of only 6dB.

I would like confirmation of the resistor values.

For information the recommended op-amp is AD8041.
