Ocean script confusion: illegal duplicate field symbol in list of fields

Hi all,

 I run ocean script for Monte Carlo simulation. In our model file, we just have mismatch parameters (the foundry do not have process variation for Monte Carlo simulation), so in order to run Monte Carlo simulation, we use for loop structure to run Monte Carlo simulation for each corners (TT, SS, FF, FS, SF). Attached please find part of the ocean script. The simulation runs successfully, however, I was confused by the results. Here is the detail,

When I open mcdata for the TT simulation, the results are fine, for the attached setting, the results are:

82.5428 32.1798

However, for the SS simulation, the results are duplicated:

81.3214 30.8723 81.3214 30.8723

If I added loop variable from 2 to 5 (cor_v=5), the duplication (duplicate the date in the same line) will be twice, three times, four times and five times corresponding to cor_v=2,3,4,5. I am wondering if any body can give me some hints about the problem?

Thanks a lot
