[WoW] Formation bug

Hello everyone i just started multiboxing using the trial pretty close to running out so i was gonna buy it soon, but i encountered a problem it started to frustrate me because i can't figure out what is wrong. One of my characters doesn't move to a formation the only one he moves to is the line one and i really don't use that one the v and x formations seem to be useful. I wanted to get everything setup before i bought isboxer so i know it was everything i wanted. Can anyone help me?
It is is4 which i found strange.

Depends on a number of things, but usually we'd need to see your profile see. viewtopic.php?f=22&t=13
The other possibility is that is that the character does not have the forward/back/strafe left/strafe right in game binds set correctly.
Sometimes it is just an oddity in that the keypress is not long enough, so hold your mouse button down a little longer. Although I'm not sure that is it in this case.
