Cut plane not cutting all Elements of exact same Family.

What could be the cause?

Object in red circle is correct.

Can't attach Revit-File yet, maybe first post.

Here is the revit file.

Revit 2021.1.3

I do not have revit atm but I assume 1 of 2 things (Either it is not cut by the view range cut plane OR the family is set to show pre-cut in plan views)...If you have already checked the view range/cut plane, Try the following:

Edit the family >> On the properties palette >> Uncheck "Show Family Pre-Cut in plan views" 

Reload into the project

Thanks a lot, it worked.
