Error message: Parameter cannot be added to the family

[Anonymous]

I am receiving the following very annoying message when creating an edit in place void which cuts a system wall.

Firstly I create a wall and I then assign a global Revit parameter to the Top Offset. 

Secondly, I create a edit in place Void geometry which cuts the wall element.

When I finish editing the edit in place element, I receive the message below.

Weirdly, when I assign the parameter after creating the void I do not get any error message.

I trust, this is a Revit bug.

Would it be possible to share any ideas why what is causing this?

Many thanks in advance.

I am getting the same issue if you use in-place family.

However if I use wall opening, it works.

Did someone mention "BUG"?  I love finding BUGS!  Bummer is, I seldom do -- including this time.  I can't seem to replicate what you two have discovered. Maybe my workflow is flawed.  Can one of you lead me through the steps to replicate the "BUG"?  Thanks in advance.

I faced this problem before with Structure wall also

I could replicate it but it seems to be an issue in Revit 2020, works with Revit 2021 though...

I confirm the above problem occurs in Revit 2020.

I don't trust any claims of bugs. They need to be proven. You might have one here but I still don't trust them.
