.txt file full of ~

Hello,
today i wanted to use Ultrasinger after a long time and just used the normal py ultrasinger.py -i (Link) command but i encountered a problem with it.

The finished .txt file is filled with 5 or more ~ after almost every word where it dosent even make sense in the song. They also are shown in the game.

Is there a way to fix that? (CPU Version)
