Never mind. I see that this particular symbol is offset. If this is really waht you need fixed, I can only recommend modifying the symbol. Not a great prospect.
I just modified this symbol. I went into Edit and transformed all the features in and across a selection window from one end of the triangle to the other. This moved it far enough to correct the offset.
Alternatively, you could explode the symbol to the drawing but then you loose the leader... and there is no undo!
