Send model from robot to Revit (cladding problem)

[WALIDGIO]

hello 
I have problem when updating the model from robot to revit when i updated a panel in robot from cladding to a normal concrete panel the revit will not reconize it , why ?

here the steps 
1 send a normal model to robot wit a concrete roof

then change the roof to cladding to exercise some analytical calculation,

when finishI change the cladding to a normal panel since the revit dont reconize cladding

then send back the model to revit with the new panel but here the problem 

the roof fis empty ???
I tryed a lot of changes to the panel but none worked

can anyone have explanation to this or can help i'll be appreciated
