If you change a fitting thru the Revit properties that is a fractional size, the product list grays out.

It does not do this if you use a size without a "/" symbol.

As an example, if you take a copper sweat 90 and swap it in with a street fitting, the product list grays out.

Which in turn, does not allow us to list the product list size in our reports.

Is this a program issue? It does this in all versions of Revit, 2020, 2021, and 2022
