Why does my wall disappear (in plan view only) when I set my window head height to 2100mm?

Using revit 2023

Ok, so I've used this window many times before. It was originally a default Autodesk one from their library and we use it in our team template at work.

However, using it in this model I'm making when I set the head height to 2100mm the wall vanishes in plan view. Still there in elevations & 3D etc. but not in plan. 

It's there when I set the height to anything other than 2100mm. 2050mm, fine. 2090mm, fine. 2099mm, FINE! 2100mm, NOPE!

It makes no sense and is really upsetting me.
Especially when it's literally there elsewhere in my model!!

Do you have plan region and what is the cut plane height?

Can you show the wall in section and it's properties?

[jasmin_dooley]

No plan region here, it's the same height as the one next to it. I literally just mirrored the walls and windows as it's the same house handed. So the view range is the exact same 😕

Hi there, 
I'll show the one that works and the one that doesn't. 
Omg I just opened it now and went to a section view and it's doing the same invisible wall thing in section for both now. Even though one is showing the wall in plan and the other isn't.

Please make this make sense it's making me lose my mind :'(

Sorry forgot to add the wall properties too

I am curious if the window family have a huge opening cut that will cut through the entire wall making it look like the wall disappear. Upload the window family.
