Hi Tiago,
Only the outline of the box seems to be incorrect, not the actual geometry.
This is a small graphical artefact bug, but nothing they would prevent you
to do any computation with the boxes.
You can switch to surface representation to see that the boxes are
correctly placed.
SetRepresentationType('Surface')
Feel free to open a bug for the outline bug on
https://gitlab.kitware.com/paraview/paraview/issues/new
Best regards,
Mathieu Westphal
