Well, the "2" key is most definitely being sent, but isn't "2" already bound to something else in game? By default, it's bound to the second button of action bar 1, so by telling ISBoxer to bind the macro to "2" it's essentially trying to "double bind" two things to "2," which isn't possible, and it's going to conflict with what's assigned to the action bar. You should see a message in the chat window stating that there is a possible conflict when you first log into the game world, or after a /reload of the UI.
So, in order to avoid a conflicting key binding you will need to choose more abstract key combinations for your macros created in ISBoxer. Most people use a combination of modifiers in addition with numbers and letters—Things that you'll never accidentally press or key bind on your own.
I reckon that if you add a combination of modifiers, say Ctrl and Alt, to the key combination of that macro it will work just fine... Unless, of course, you have something already bound to Ctrl+Alt+2 in the game.
