Inconsistent translation

[Clara AD]

Why are some lyrics in romaji written in uppercase that they don't match English translation?



Here's an example:

Japanese lyrics: Mukashi nagara no SAIDAA no naka ni nemuru kokoro no tama
English translation
-In the cider of the past, the sphere of my heart sleeps
-Supposed lyrics: In the CIDER of the past, the sphere of my heart sleep

[Fuukanou]

Old transliteration convention indicates katakana words are meant to be romanised in caps, but there is no such convention for translations. As a result it's just saying the word サイダー is katakana.
