nonlinear-map from trackin

Hi,
I am trying to get the non-linear one turn from from tracking. The script I am following is from elegant examples "ILMatrixFromTracking/"
The attached files are what I am using right now. In current stage, only two steps are included.
step 1, with the Basic.ele, the required chromaticity (5,5) is set, after running Basic.ele, the updated lattice parameter in saved in Basic.param, which is supposed to give chromaticity value (5,5)
setp 2, in closedOrbit.ele file, the Basic.param obtained from the step 1 is imported in, then it is used to get the closed orbit as a function of momentum derivation \delta. For each momentum, the main lattice information is printed out to the closedOrbit.twi file.
Here is my question: in the closedOrbit.twi file, I found the chromaticity in the first page are the values as I set (5,5), whereas in other pages, the chromaticity are (6,6)-- not the value I want to study
Is anything wrong in my script, or what should be improved to make the chromaticity correct in all pages in closedOrbit.twi.
