Missing something basic here with the ISBoxer Wow Macro Sets

[Blackwater]

OK it has been a long time since I delved into ISBoxer, so please be patient with me.

I was reading up on wow macro sets.
I created a simple macro to test how to use it.
I have made sure that on both toons ISBoxer is checked under addons.

So under the macro sets I made a new one called Pally. I have enabled the macros for the 2 Pallies character set and have highlighted both characters.
Under that it is a New Wow Macro. That macro has just /s omg in it.
I have make the key combo Num1.
Saved it, Exported it.

The screen flips, so I know it has updated wow.

I hit Num1, and only one character is saying it. The character that I am currently controlling.

Where am I going wrong?
