[Unsolved] Custom unit sounds!

[Emberhammer]

I'm trying to add custom unit sounds, but for some reason, they won't work properly. EVERY unit in the group plays a sound whenever the group is issued an order!
I can't remove sounds (from the actor) either...

I've included a picture of the Marine actor. Weel, at least the sound parts that I edited.
What am I doing wrong?

Please help!
