I'm using a macro to create custom properties that reference Cut List properties, but they are displaying the formula rather than the evaluated result...

Cut List Property:

Custom Property:

EDIT: I noticed that there are some parts where this feature does work, and the cut list / file custom property menus appear different. I do not know why, but there may be a connection?

EDIT 2: Fixed it. For others who might encounter this, I had to add a line to my macro: "swModel.Extension.UpgradeLegacyCustomProperties True".

This can also be done by right-clicking on the topmost item of the feature tree.
