These were uploaded before the songs were actually released.
The first, Yakusoku no Kizuna, has not been released yet; as it is not on the OP/ED singles or the first character song CD, the earliest possible release is December 11, more likely January 8. (See release list for Kyoukai no Kanata.) Note that the transliteration contains only one whole A-melody / B-melody / chorus sequence, followed by a final chorus - the length that appears in the episode, and almost definitely incomplete.
The second, Daisy, was uploaded about a day before the single was released (today). It appears to have been lifted straight from the Kyoukai no Kanata wiki, whose version is an amalgamation of UTW's TV-size translation (complete with the clear mishearing of 'start line' as 'sa try') and a transcription from leaked booklet scans with errors (including some seemingly deliberate ones to keep the chorus consistent with the fansubs).
