Variable input extension bug

[Carlaf_93]

I'm using the variable input extension to modify some variables directly in the dashboard's area. 

So i insert a value in the input variable box and i save it in a qvd file to store it.

When i recall the qvd file the value is shown correctly in a table or kpy but not in the 'input variable box'. 

Is it a bug? How can i solve it?
