I realized that it is not the code itself that is causing the problem,
but something that is happening before. Because, when I ran this code
independently on the data with only the variables used in the code,
the results are same all the time. I need to figure out what else is
going on before this particular code. I will update if I find the
answer.
Thank you for your time.
Regards,
Rijo.
