Hi Paraview,  
I found this clip closed surface filter is not working on contour filter.

Here’s the information of the pipeline.

Is it normal or do I miss something?  
Thank you!

This looks like a bug, I was able to reproduce with the following steps:

- `FastUniformGrid`
- `Contour`
  - on `DistanceSquared`
  - value `50`
  - output looks like a sphere

- `ClipClosedSurface`

In the same time, `ClipClosedSurface` on a `Sphere` works as exected.
