Hi,

I recommend looking at the output of the "Viterbi" option available at https://www.atilika.com/en/kuromoji/ to see what's going on. It seems that for IPADic (default dictionary) there is a connection weight that highly values the connection between 数 and 接尾 (i.e., regarding it as a number + 人).
If you look at the result using UniDic, it outputs "一人" (ひとり) so the naive solution is to simply switch using UniDic.
