different results in a co-simulation

I have currently a problem with a co-simulation in ADS . I have designed a coplanar waveguide in Momentum and simulated it. For optimization I wanted to start a parameter sweep. So I exported the design from Momentum and did the same simulation in ADS Schematic. The results where not the same! I had a similar lowpass curve, but with two instead of one ripple and  more attenuation in the passband. When I started the simulation ADS Schematic opened the Momentum window and did all the simulation in Momentum. So why can there be any differences? I tried neary every possible setting, but still the results were different.
