Naming scheme

Nuendo is adding an extra character to the file name when I export. The file name is very important. I run an Auto Hot Key script that re-arranges things but Nuendo is adding a character. What is going on. Maybe I have to do a clean install

Here is the file name:
Asia20 Kims New House v1

I do 3 export mixes, Full Mix, SOT Mix, M&E mix.
Here is what I want: Asia20 Kims New House v1 - Full mix.wav
Here is what I get: Asia20 Kims New House v1 – full mix.wav
