[Ifeffit] How is the path data exported?

Hello, I just started to use Artemis again and at the moment I am a bit confused about the results. In one Artemis experiment I just select two FEFF-paths and choose a "sum of paths" which produces the result shown in the appended picture (SumOfPaths2). Shouldn't the fit be more or less look like the sum of the two paths? I also exported both paths as chi(k)-data and manually added them which produced the same result as the chi(k) of the fit. But when I use more paths I get a different result: the manually summed chi has a greater amplitude (see chi.png). Could that be related to the fact that the fit parameters are applied to the sum of path but not to the exported paths? Cheers Gerrit
