Not all selected objects are classified

I have prepared the SQLite database through the Cell Profiler, then I prepared the training set (100 positive, 100 negative objects from 27286 selected objects). I trained it and finally with 15 rules I got F1 score 0,93. Then I pressed Score all button. I got the table with enrichment score, but I need also table with information about each selected object whether it is positive or negative class. I loaded it from database as – MyExpt_ but I found out that from all 27286 selected objects the program classified only 5050 (negative – 4175, positive – 875). Others were marked as - NONE.
Please may you help me somebody what is the problem? It seems the classification is not finished for all selected objects from database. Thank you very much, Janka
