How to fix a Barred Gate door with balusters showing a mask in Elevations?

[JsphH11]

I'm trying to model a gate door with balusters. 

On the left is the 3D and on the Right the elevation.  I placed a wall behind it with a lower height. In 3D, the wall can be seen beyond the door whilst in elevations there is a mask I can't find that mask item, in the family editor. 

I attached the Revit Project (2023), Thanks in advance. I hope this not a default revit thing

Hi,

Select the opening cut in your family and make it transparant in elevation:
