ROM Hack KH3D Undub question

[Mylink5]

Hello! I am trying to make an undub for Kingdom Hearts 3D. I replaced the sound files, recompiled the rom etc. I start the game, it runs perfectly, and the japanese voices are ther. BUT the voices stop at the end of the sentence. It's like "My name is not ------" "It's ----" Where do you think the raft --------" (ofc in japanese ) Does anyone might have an idea on what might the problem be?
