Good news, your FTL Assist Me and FTL Modifiers are default. Your config shows that the problem is in WoW, not in ISBoxer.
If you switch to slot 5 and the others don't assist him but your guys assist all other slots, there MUST be some key binding in WoW using Ctrl+Shift+Backspace in the windows that will not assist that character (the FTL Modifiers for the Slot, plus the Key Combination configured for FTL Assist Me). You reset the key bindings to default (on all windows?), so that really shouldn't be a problem. Try disabling WoW Addons except for the ISBoxer Addon?
This works on all slots out of the box on a clean WoW, so as a last resort what you can do is reset the key bindings on all, disable all WoW Addons on all except for the ISBoxer Addon, and go back and clear your ISBoxer config and run the Quick Setup Wizard again. After observing it work on all slots, then you can turn other Addons back on and make other changes and if something interferes again, at least you should have an idea of what the problem might be.
