Problem while Editing Multiple Weld Points created in Weld Assistant

Hi, 

After creating Weld points, when I try to edit multiple weldpoints at the same time then "Edit Parameters" is opening expressions. There should be "Weld Point Wizard" window to get opened.                                                                              Following is the problem

Problem_Editing_multiple_Weldpoints                                              And I am able to edit single Weld point created as below-

Able_to_edit_single_Weld point.

Please help!

Thanks and Regards,
