Variable List- Data Disappear after closing visio

[rajeevk0001]

Hi ,
I have created many variable list.
I have created templates using shape data and in that shapes defined many variable lists.
Whenever I use that template and If I enter any data manually (by typing ) visio allow me to enter and save.
But the text I enter manually (shape data)disappears whenever I save and close that drawing.
I have given default value also in that variable list.
Next time when I open drawing instead of stored text on shape data default value appears.
