Solved Theme Builder model behaves differently when assigned to 404

Hi !
Just beginning with Divi (and wordpress development).

I've just try to create a new 404 model on Theme Builder (copied from the model used for other pages).
I've assigned this model for "404 page" and also for a static page, to compare.

The same model behaves differently on both :

• when browsing on the staticpage, i've got the normal behaviour
• when browsing on 404 error, i've got huge differences : menu items are displayed vertically, search icon is replaced by a form input and a button, on the footer where i have normally 2 rows, the second is under the first, ...
  It's all like my browser (Chrome on PC) was detected as a mobile one, with small width ... or something like that.
  And, again, it's working like a charm if I go back on the static page.
  The problem is the same on header, body or footer (I try to put menu on each).

I've got the exact same behavior when trying to create a Search Page model.

Is this a bug, or am I missing an extra parameter somewhere ?

 

Yes ! Thank you, it's working well now !
