Different result to NO3 in calibration and validation

[diego huanquiao]

Hi everyone,

I need help, I calibrated and validated nutrients (NO3, NO2, Nitrogens and phosphorus), with periods of 2004 - 2010 and 2011 - 2019, respectively. 

the problem is that I calibrate and validate the nutrients separately, and then I try to calibrate and validate them all together but nitrate is the only one that changes its results in the objective functions, attached results and file File.cio.

I have tried in many ways, modifying the File.cio file and others, but they always give me the same results, except nitrate.
