I am creating an array of SimulationInput objects, 'simIn'. If I try to run a single simulation, for example using simOut(1) = sim(simIn(1)) to run the first case, why does simIn lose all other array elementes. It changes to a 1x1 SimulationInput object, whereas before the sim command it was a 1x28 object

for casenumber = 1:NumFile
    if ~isempty(char(file{FileIdx(casenumber),1}))
        if exist(strrep(char(file{FileIdx(casenumber),1}), ';', ''), 'file')
            
            %% Setup parallel Simulation
            
            simIn(casenumber)=Simulink.SimulationInput('XWB_MSL_EEC');
            simIn(casenumber) = simIn(casenumber).setVariable('Experiment',Experiment);
            simIn(casenumber) = simIn(casenumber).setVariable('Enable_MSL_Validation_Logging',Enable_MSL_Validation_Logging);
            simIn(casenumber) = simIn(casenumber).setVariable('SimStartTime',0);
            simIn(casenumber) = simIn(casenumber).setVariable('TimeMode1',TimeMode1);
            simIn(casenumber) = simIn(casenumber).setVariable('TimeMode2',TimeMode2);
            simIn(casenumber) = simIn(casenumber).setVariable('parallel_casenumber',casenumber);
            simIn(casenumber) = simIn(casenumber).setVariable('ModelPath',ModelPath);
            simIn(casenumber) = simIn(casenumber).setVariable('toolGitStatus',toolGitStatus);
            simIn(casenumber) = simIn(casenumber).setVariable('configGitStatus',configGitStatus);
            simIn(casenumber) = simIn(casenumber).setVariable('toolConfigVersion',toolConfigVersion);
            simIn(casenumber) = simIn(casenumber).setVariable('configGitInfo',configGitInfo);
            simIn(casenumber) = simIn(casenumber).setVariable('switchBatchMode',switchBatchMode);
            simIn(casenumber) = simIn(casenumber).setVariable('resultsDir',resultsDir);
            simIn(casenumber) = simIn(casenumber).setVariable('switchExportDataToPhobos',switchExportDataToPhobos);
            if ~isempty(Suffix)
                simIn(casenumber) = simIn(casenumber).setVariable('CurveName',sprintf('%s_%s',file{FileIdx(casenumber),1},Suffix));
            else
                simIn(casenumber) = simIn(casenumber).setVariable('CurveName',file{FileIdx(casenumber),1});
            end
            
            % Use a temporary variable for the SimIn element to avoid runaway memory usage when using a preSimFcn with parsim
            tmpSimIn = simIn(casenumber);
            
            preSimFcnInputs = {file{FileIdx(casenumber)}, tmpSimIn};
            simIn(casenumber)=simIn(casenumber).setPreSimFcn(@(x) parsimMSLPreSimFcn(preSimFcnInputs));
            simIn(casenumber) = simIn(casenumber).setPostSimFcn(@(y) parsimMSLPostSimFcn(y, tmpSimIn));
        else
            error(['Could not find Case "',strrep(char(file{FileIdx(casenumber),1}), ';', ''),'"!'])
        end
    end
end
