Help - facearea

[Edsacchi]

Hello, good morning, everyone.
My name is Edgar, I'm an architect here in Brazil.
I'm new here and I'm asking for some help.
I created a dynamic component of a wall, I need to take the area of a face of it, why when I stretch or raise the wall, the area of the wall does not update in the component option panel?
To update the area I always have to enter the attributes component and click on the formula for the account to be redone, then yes it changes in the option panel of the component,
Please, I need automatic change, thank you very much.

otherwise if specific you need to upload your component (private if required, note I will be away two days)
