Did you reassigned the bind for Autorun/Autofire in DeusKeyBinds.cs?
Try resetting those to whatever you want them to be, then manually put this into your config.cs:
bindAction(keyboard0, make, "a", TO, IDACTION_MOVELEFT, 1.000000);
bindAction(keyboard0, break, "a", TO, IDACTION_MOVELEFT, 0.000000);
