Native Bayes Kernel - no prediction in few examples

Naive Bayes Kernel operator, after finished classification, marks few predictions as "?". What can be cause of it? It can't find any similarities with rest of examples?

My csv looks like:
id, author_id, characters_number, words_number, average_sentence_length, average_word_length, ratio_unique_words, ratio_word_length_1, ratio_word_length_2, ratio_word_length_3, ratio_word_length_4, ratio_word_length_5, ratio_word_length_6, ratio_word_length_7, ratio_word_length_8, ratio_word_length_9, ratio_word_length_10, ratio_word_length_11, ratio_word_length_12, ratio_word_length_13, ratio_word_length_14, ratio_word_length_15, ratio_word_length_16, most_used_word_1, most_used_word_2, most_used_word_3, most_used_word_4
"100395", "1000866", "1640", "318", "44", "3,94", "0,6006289", "0,08805031", "0,1761006", "0,1949686", "0,2327044", "0,1069182", "0,07861635", "0,06289309", "0,02515723", "0,01257862", "0,01886792", "0,003144654", "0", "0", "0", "0", "0", "anyway", "really", "decided", "write"

    Ok, thanks. My whole csv has 500 records. There is no nulls. So I think it is because operator can't find any similarities for given set of records.
