Issue with MLEADER objects on different elevations

I have some drawings with MLEADER objects on different various elevations, so when you print the drawing out the text is thicker than the MLEADER objects that is on elevation "0".

Since mleader object have no physical x.y.z when you look at them in the properties box, how does one go about moving them down to elevation "0"?

The flatten object found under express tools explodes them in to lines and mtext, so it is not an option.

Thanks
