Solid Edge Created Planes such as Parallel, Normal to Curve or Tangent appear at the model but not in the PathFinder

The user creates some Planes such as Parallel, Normal to Curve or Tangent and notices that whilst the resulting planes appear on the model in the graphics window, they are not listed as items in the PathFinder as expected.

How can they be made visible again in the PathFinder?

The Planes can be easily made visible again as follows:

• Move the mouse cursor over the part name in the PathFinder.
• Execute a right-click (Right-Mouse-Button) to open the context menu.
• Select 'Ordered PathFinder Display'.
• Notice that the 'Planes' option is unexpectedly disabled.

• Enable the option.
• Notice that the Planes are now listed as items in the PathFinder again.
