About CPML boundary conditions

Dear all,
After I used xadd_CPML_layers_to_an_existing_mesh and xconvert_external_layers_of_a_given_mesh_to_CPML_layers to convert the grid file of tpv5, when I run it again, it appears “STOP Inconsistent fault mesh: corresponding node in the other fault face was not found”,What should I do to fix this error??
