As I recall from [one of your previous posts](https://discourse.paraview.org/t/boundary-edges-not-recognized/11349), your data comes from a DG simulation. I don’t know the details of how `Ghost Cells Generator` works, but I suspect that once again the discontinuous nature of your data is interfering with finding correct matches.

The first thing to try is to run `Clean to Grid` _first_ and then `Ghost Cells Generator`. The generator might not be checking for duplicate points on each process.

I expect `Ghost Cells Generator` will use global ids if you have them. I would expect global ids on discontinuous boundaries would mess up the ghost cell generation. If you have them, you can try deleting them. You might be able to use the `Pass Arrays` filter to do that.
