I think you're using training image labeler to label you positive images, so instead of using the struct directly split only the information that belong to the bath and the ROIs . you can try this

load('LabelingSession.mat');
data =  labelingSession.ImageSet.ImageStruct;
trainCascadeObjectDetector('yourfile.xml',data,negativeFolder,'FalseAlarmRate',0.5,'NumCascadeStages',25, 'FeatureType','Haar','ObjectTrainingSize',[20 20]);

Hope it helps . greetings
