Welcome to the forum @U17208099.
The official language here is English, which is a requirement for search to work or I would practice my Swedish in all my replies. Please translate your posts in the future using a translation service of your choice. You can keep the original post as well, but separate it from the translation as I did in the edit to your post.
Can you show the inputs for the wall node?
Have you checked to see if the walls are hidden by a filter or a phase?
Try selecting the elements by Id in Revit. They could be hidden in view for any number of reasons.
Could also check the workset it’s being created on, perhaps it’s closed or default hidden.
