Character Glitch

[Beast King Barbaros]

I have a problem with the character Yoriko Yasuzumi
MVC Stile arrangement of the author "Uru".
When I play with her and stay close to the opponent, then she starts using dash like crazy, so I can not control her any more.
I wish someone would fix this, or give me a hint of how to do it.
I do understand a little CNS file, but to my frustration, not enough.
It's a great pity not to be able to use it because it's a great character.
Every help is welcome.
