OPM SS6 managing welds in isos, display welds between new and existing piping in the weld table

When I'm making tie-ins to existing piping I used to mark existing pipes status as "for demolition" so I can attach new piping to those but they will not in the Bill of Materials. (I'm not sure is this proper do this)

Anyway I have now a problem that welds between the new piping and old piping will not show in the weld table, marked with red in the screenshot below. Welds are in the model correctly but they are not at the weld table.
