bug or feature ?

Three pages of kanji definitions have the first meaning repeated, but the second lost.

三 4E09, 23, three, three ; %e4%b8%89
上 4E0A, 37, above, above, up ; %e4%b8%8a
下 4E0B, 7, below, below, down, descend, give, low, inferior ; %e4%b8%8b
不 4E0D, 572, negative, negative, non-, bad, ugly, clumsy ; %e4%b8%8d
 
Yet somehow the first meaning is more eye-catching for me. An unintended feature ?
