Autocad 2012 Multileader copy and editing problems

I have searched everywhere for this problem but so far no one's every mentioned it.

Here's my problem:

I'm using a modified version of Edwin's Prakoso "Automatic Coordinate Labeling" Lisp routine. I'm using multileaders instead of leaders.

I have set up the multileader style for it to appear vertically.

The problem is when I copy those multileaders from one drawing file to another, the lines of the multileader "extends" itself beyond the text, like so:

Another problem arises when I try to edit the multileader text, or when I changed something in the Multileader style dialog box. The lines "extend" themselves before the text like so. This extension is indefinite, it go on and on.

Can you upload a sample drawing for us to take a look at? Thanks!

Could something in the lisp routine effect it? It may be something we can't fix because it might be a software issue.

Here's a sample and the lisp I'm using:

; Automatic coordinate labeling
; Edwin Prakoso
; http://cad-notes.com
;
; Limitation
; ----------
; Will use current leader style and current units setting

(defun c:ll (/  p y x ptcoord textloc)
 (while
   (setq p (getpoint "\nPick Point: "))
   (setq textloc (getpoint "\nPick Label Location: "))
   (setq x (rtos (car p)))
   (setq y (rtos (cadr p)))
   (setq ptcoord (strcat "{\\H0.70x;\\S" y "/" x ";}\ "))
   (command "_MLEADER" p textloc ptcoord "")
 )
)

10 mins after posting the thread, I realized I could just use QLEADER and MTEXT in my lisp instead of MLEADER for the same goal. And without the "line extending" copying/editing bug.
