Steps:

1. Engaged Notorious Monster "Unknown Soldier".
2. Sometime in the middle of the battle I engaged monster "Sea Puk". The name of the monster "Sea Puk" kept yellow while the name of the monster "Unknown Soldier" remained red (as usually).
3. Defeated monster "Sea Puk" and used Siphon MP II on it.
4. Changed target to Unknown Soldier and the combat music turned off in a sudden and remained this way for the rest of the battle.

Maybe it was just a pretty occasionally issue and lacks of importance, so there's no need to take this into consideration. Feel free to close the thread if that's the case.
