"The process inside loop operator gathered different results from outside loop"

I used loop parameters and macro operator to test the effect of NN hidden layer size to classification accuracy. Loop operator produced all the results and I learned optimum hidden layer size.

When I set up  the same parameters in different process, it achieved different results from loop operator's results.

My data  201x7000 matrix. it contains 200 real atribute, one class label, 7000 sample.

For example this process saves all results for NN whose hidden layer sizes: 2,4,6,8,10,12,14,16,18,20.

this process saves only one results for NN whose hidden layer sizes is 10. but it is different from prevus results. All parameters and input data are the same.
What is the problem?
