Error in jEPlus EA when conducting optimization

Hi, I am trying to conduct an optimization with a sample DOE large office reference building using jEPlus EA. I developed my parameters of interest using jEPlus and have obtained results with no problem. But when trying to conduct the optimization simulations with jEPlus EA I get below errors. The model is developed for a small test I did by changing cooling set point temperatures for small sample size. O can see the EnergyPlus output results but somehow I cannot see the graphs (especially Pareto Front that I need).

Does anyone have any suggestions?

Error:

"Simulation results contain the following errors:

C-0_0_3 - case is missing - no results available

C-0_0_2 - case is missing - no results available

C-0_0_1 - case is missing - no results available

C-0_0_0 - case is missing - no results available

C-0_0_4 - case is missing - no results available"

After couple more days of working with it finally found the issue. I am using E+9.1 and had to convert the DOE reference building to this version. Somehow at some point of my work the E+ "OutputControl:Table:Style" object was set to "HTML" only. Where jEPlus+EA relies on .CSV output tables to extract the information for the analysis (sensitivity, optimization, etc.). So after changing the E+ model object to "CommaAndHTML" the issue was resolved (since now I get both .html tables and .csv which both are the same info just different format).

Note: This change needs to be done in the .idf (or the note) file and then imported to jEPlus to work.
